(refs #7042) Added a new compiler optimization (eta-reduce)
Adds new optimization to SCL compiler that transforms the following code
\someParameters = f someOtherParameters someParameters'
to
f someOtherParameters
with the following restrictions:
* someParameters and someParameters' are lists of equal variables
or the type is ()
* someOtherParameters does not refer to variables in someParameters
or the lambda expression itself or something depending on it
recursively

Added module header feature to SCL language.
Module header must be in the beginning of the module. However, comments
are allowed before the header. Header has the following form:
module {
field = value,
field = value
}
Currently field name classLoader is supported. It makes it possible to
specify which classLoader is used to resolve importJava declarations.
module {
classLoader = "my.bundle.name.somewhere"
}

Removed logging of PendingVariableExceptions from LabelContribution
org.simantics.browsing.ui.model.labels.LabelContribution.getLabel used

PendingVariableException prints in normal operation.
PendingVariableExceptions are expected to happen in this context and
therefore should simply be ignored by returning empty labeling results.

Issues-view menu improvements & Variable-based issue context resolution
This adds a new [Resource] valued property for Issue instances that is
by default defined to just read the old Issue.HasContexts L0.List
property. The property allows for more specific domains to override the
issue context resource calculations.
To support this calculation a noteworthy change needed to be made to
org.simantics.db.layer0.function.All.getStandardChildDomainPropertyVariable.
It now performs a new final fallback step that resembles how the
standard procedural variables work. If the parent variable has a solver
variable node defined, it will use NodeManager.getClassifications as an
attempt to read the type Resource of the variable. If this is
successful, the asserted properties of the type are searched to find a
property matching name of the the requested property. To support this a
new request was added: UnescapedAssertedPropertyMapOfResource. This
request is also used to optimize the implementation of
All.standardGetValue[12].
These changes also add a Help action for Issues view context menu that
looks for the "contextHelpId" String property from the Variable
describing the issue.

Fixed memory leaks of SCL module listening systems
The main addition in this change are backlinks from UpdateListeners to
Observables. They make it possible to implement
UpdateListener.stopListening that removes the listener from all
Observables. This method is called automatically before the listener is
notified about the change, but client code can also call it when it
becames disinterested about changes.
Because now the client code is reposible for signaling when the
listening stops, the listeners are no more store to WeakHashMap in
ModuleEntry.
This change also contains a change in the default imports of some graph
based modules (Prelude -> StandardLibrary).

Removed unwanted and broken toolbar contributions
These innocent toolbar menuContribution extensions seem to have been the

Fixed component type editor Lift Properties domain setting.
Previously Lift Properties would copy the lifted property relation over
to the user component type as-is which would also leave all the existing
L0.HasDomain relations of the relation in the copy. This can cause
totally unwanted HasDomain definitions in the property relations which
in turn can cause unexpected export-import problems later because of
those unexpected dependencies.
This changes the code to first remove all the existing HasDomain
definitions from the copied property relation and then add the HasDomain
relation to the target component type.

Fixed IEditorPart reference (memory) leaks from ResourceEditorSupport
ResourceEditorSupport.validationRequest gave IEditorPart as an argument
to UnaryRequest which caused the reference to remain in the DB client's

with editors that require a lot of memory and never explicitly free

Improved error handling in shared library import wizard
Previously the wizard catched all exceptions in the wrong place causing
the UI to never show any errors to the user and just close the wizard as
if everything was successful. The problems were only printed to the
console and in selected cases also to the workspace error log.
This changes the import code to not catch any exceptions and let the UI
side deal with the thrown exceptions by logging them, showing them to
the user as the wizard's error message and in a separate error dialog.
