Run some commands synchronously. This avoids issues with the UI
reacting to file changes done by the VCS on windows which can lead
to crashes.

Allow to do codefolding on files and hunks in the diff editor

... instead of running a sed script over a lot of files on each
version increment.

qtLibraryTarget is only defined if used with TEMPLATE=lib, which makes
it fail in pri files that are used for app pro files. The tests still
don't run because of run time linking issues.

Bring the submit to the front when asking whether the change should
get committed or not. This is useful when e.g. closing creator
while a submiteditor is open somewhere (but not visible).

Abort a commit when pressing ESC in the "Do you want to commit?" dialog.

Should have been done earlier. 2.1.80 was burned in the pre-2.1.0->2.0.1
days, and we'd like to have odd subminor for 'working' and even subminor
numbers for pure cherry-picking release branches anyway.

Also introduce a indirection, modes have now types, edit and debug have
the same type, and editors do have a prefered type of modes instead of a
prefered mode.

That fixes the bug that if the prefered qml editing mode was set to
design, then in switching between qml editors would
- in Edit Mode: stay in edit mode
- in Debug Mode: switch to debug mode

The function always switched to Edit Mode, which was the cause for
several bugs. Since openEditor() already does switch to the right mode,
the function is not really needed.

The following actions now respect the prefered mode of the editor:
"f file"-locator
The Open Documents list
Editor history navigation

 * Fix all warnings about non-explicit constructors except for those
   in 3rdparty code.
