Use the defined foreground for search scope instead of calculating
something from background. Support empty foreground for the standard
selections (allows us to match certain popular colorschemes)

Block selection was "broken" when using tabs, or rather
incomplete: It treated tabs as normal characters, which
has shown to be unexpected by people using tabs in code.

The new implementation has a vastly improved find scope
as well. In addition, creating a blog selection with
mouse or keyboard feels a lot more solid now, as the
actual selection is detached from possible valid cursor
positions.

There should be no need for the text editor to request an update of the
completion box, since when it's there it will have focus and update
itself.

It gets a little too colorful.

Using more *::Constants::ICON_* where it makes sense and
wrapping the file names into QLatin1String where they were
missing.

The increased usage of the ICON constants needed a few more
cross plugin includes of *constants.h, here and there.
I think that it is OK, since the dependencies were alredy there
icon resource wise.

For answers to questions about where to insert a snippet/chunk of C++ code. Ok,
currently it will only find the One And Only place to insert method
declarations in classes, and it will need some tuning.

Required refactoring of the search result window to show real trees of
search results.

The backend is the backend from the Locator filter, which is a bit
outdated now.

Fixes that the filter button could be 'checked' for a cpp file.

Make it the same order as in the Projects sidebar

The old integration option is now used to switch to extended descriptions.
