Add repository creation operation to IVersionControl, implement for hg
and git, add convenience slot with prompts to VCSBasePlugin.
Add respective menu options and make menus are visible in case no VCS is
active.
Change project wizards extension page to list VCS that are capable of
repository creation in a QComboBox in case the directory is not managed
by another VCS (in which case it lists that one for operation 'add').
On that occasion, polish the Project selection to use a QComboBox as
well and add some smartness to find the most suitable project to add via
path matching.

they were remnants of the pro editor, which was removed long time ago.
they were still used for automatic editing of pro files, but were
totally overengineered for that purpose (removed 1300 LOC, added 40).

Look at the token under cursor only if the current character is a brace or a quote.

Task-Nr: QTCREATORBUG-459

Do not allow users to edit the field right beside the visible checkbox.

Happened when trying to reparent a node to one of it's children.

Task-number:   BAUHAUS-276

registerDocumentation failed if a namespace/qch file had been registered
before, but the qch file is not accessible any more. This prevented
the registration of the same namespace/qch file at a different location.

Fix this by explicitly removing entries that have no valid qch file any
more from the db.

The usage of 'int newIndex' was ambiguous in the case of
oldIndex < newIndex. Solved by directly passing the ModelNode that was
moved around.

'nodeSlidedToIndex' was also renamed to 'nodeOrderChanged', since
'Slided' is no proper English.

The custom creator-qml installer comes with a qmlviewer installed
in creator/bin. Make sure that this qmlviewer is used to run .qmlproject
files, even though there might be other qmlviewer binaries in the
PATH.

QMake passes those headers directly to gcc, so the user doesn't need to
include themselves.
