These icons adds visual clutter and do not really give any
added value. We should reserve icons for lines that are
known as errors or warnings as these deserve special
attention.

Re-introduce FormWindowEditor as IEditor used for
Designer. Use SharedTools::WidgetHost directly
for embedding into FormEditorStack, doing the
geometry-changed handling in there as well.

We need this for translations.
I also added the label to the tool tip.

The original logic was faulty but worked better in the presence of the
original "extra layoutChanged()" hack which is replaced now.

Also make sure it searches for the best match in all files that define
potential matching definitions.

Added compatibility scores to functions - candidates to switch to

Fixed crash in FindUsages on a dirty file in a large project, which is saved
while the FindUsages is still running.

Custom Executable RunConfiguation assumed that there is always a active
buildconfiguration which is simply not true for qml projects.

Also fix a small bug that the executable was not searched in the full
environment but only in the build environment.

Move resource code to new ResourceHandler class and
instantiate it on the form window.

Re-introduce FormEditorFile that delegates dirty handling to the form
window. Change DesignerXmlEditable to be an IEditor that embeds
TextEditable so that the PlainTextEditor can work with it, but delegates
relevant functionality to FormEditorFile.
Centralize all form window creation code that was scattered around
in FormEditorW::createEditor() and have that return a struct Editor
data, which is passed to FormEditorStack.
Update the text editor only on open/createNew/switch away from design
mode.

 ... not if it is null.

Using non capitalized text this time as this is
what we have decided to standardize on for future versions.

Changing anything in the submodel right now crashes, and it seems
it will take some time to fix this.

This kills the event filter since it is not really neccessary.
Most combo boxes should be disabled by default now. I Removed
redundant focus widgets from the keyboard chain and I
indicate that the list has focus by saturation.

- Remove shared subwindow reparenting from EditorWidget, make EditorWidget
  inherit FancyMainWindow. and use just once instance of it instead of
  per-editor ones.
- Embedded FormEditorStack into EditorWidget as a centralwidget.
- Changed FormWindowEditor's base class from IEditor to SharedTools::FormWindowHost
  (Widget) to be embedded into FormEditorStack (no need to be an IEditor),
  Remove Designer::Internal::FormWindowHost which had little functionality.
- Add Design Mode widget to FormEditorW which has FakeToolBar and EditorWidget
  (single instance) in a vertical layout.
- Removed ProxyAction class handling dock view toggle actions of several EditorWidgets
  (no longer necessary since there is just once instance). Moved "View menu" to bottom.
- Started to make FakeToolBar work as a single instance listening on changing
  xml editors
- Include-file/slot connection clean-up.
