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

Implement in git.

Add missing menu options for project/repository actions. Add support for
'edit' (current file) and 'unedit' (current file/repository, with
prompt).
Note: Unediting modified files will only work with cvsnt, since it uses
the '-y' option to force a 'yes' to CVS asking to revert changes.
Implement IVersionControl::vcsOpen() by using 'edit', causing it to
prompt for read-only as it does for Perforce.

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.
