Diagram export filepaths are now prefixed with the containing model
namespace to avoid name collisions.

[ui.structure] Simplify inheriting actor positioning

[core.room] fix binding validation to check inherited external end ports

Closes #46

See merge request !15

Validation for connection of external end ports now also accounts for
inherited ports. Note that due to current scope provider behavior, it is
not actually possible in the textual editor to encounter this case.
HOWEVER, it does become an issue in the diagram editor, because it
currently uses ValidationUtil on arbitrary ports in the diagram without
consulting the scope.

Issue #46

[team] add gitlab remote to git clone task in ETrice.setup

Closes #35

See merge request !9

- clean up of git clone tasks
- hardcoded website repo location folder to workaround same-named repo
locations
- added missing dependency for lsp4j sdk feature
- added missing java modellib/runtime import required for tests

Issue #35

Pos and PosAndSize are moved up to ui.structure.support package, since
they are referenced in DiagramUtil API which can be accessed from
outside of the bundle. This allows e.g. the tests to use DiagramUtil
without package access restrictions.

The following are restricted if inherited:
- Update/resize of ActorContainerRefs
- Move of InterfaceItems on actor refs
- InterfaceItem text label positions

- minimum resize is restricted to external port locations
- external ports retain their positions along the structure class edge
when resized or updated
- inherited binding bendpoints are updated during resize to keep
positions relative to base class

- Inherited actor diagrams always take the layout of the base diagram
- On open/update, diagram will be resized to base diagram size if
smaller than base diagram
- No scaling of base actor elements will be done during resize/layout

[ui] support keyword hover for enum keywords

Disable warning for non-existent modelpath entries

See merge request !3

If the modelpath contains directories that don't exist, we currently log
a warning. However, in practice missing directories are not really a
problem. Therefore we only log a debug message instead.
