Clean icore.h.

Task-number: QTCREATORBUG-2929

String update as suggested by Leena.

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

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

- Use standard execution log entries in all VCS plugins (outputwindow).

Merge managesDirectory() and findTopLevelForDirectory()
into one giving managesDirectory() an optional topLevel
parameter. This removes the need to go up the directory
hierarchy twice when checking for Merurial or git and also
saves some checks for CVS/Subversion.

Ensure clean paths are returned by
IVersionControl::findTopLevelForDirectory() as otherwise caching
of VCSManager breaks (Windows) and commands are executed all over
again. Fix display in SVN/CVS.

We now support renaming files. The version control system tries first to
rename, if that doesn't support or can't rename the file we do a normal
rename. (Note: git, hg, perforce > 2009.02 support renaming, cvs not.
(perforce untested)). We correctly notify all editors of the renamed
file and tell the project manager to rename the file in the project.

Note: Only the qt4projectmanager knows how to rename files.

Note: renaming folders, moving files to different folders, renaming
.pro/.pri files is not supported. Those things can be later added after
this has proven to work correctly in the simple case.

Also we don't do any actions based on the renaming like renaming
classes, changing include guards or #include lines.

Add menu options for consistency, run
svn in C-locale.
