Option for  TortoiseSVN to avoid hassle with other IDEs.

Reduce inconsistencies in tr()-Strings provided for
QActions that act on a current <something> (mostly files) by
introducing a ParameterAction class that takes the tr()-Strings
at construction time and provides a setParameter(QString) slot,
allows for setting that parameter or an empty string, which
will cause the displayed text to be updated.

i don't think it is a good idea to tr() the svn command in the dialog
title

Handle modified 'status' formatting (starting at column 8).

Details: Use a global model for nicknames that is shared by all dialogs to solve the updating  problems. Make p4 plugin submit work again. Force a submit prompt in case of shutdown or editor close (as opposed to user clickling on "Submit").

Fixes: Add common configuration to the VCSA base plugin; submit message check script and user name configuration.                                           Details: Extend submit editor widget by configureable fields. Use them in the VCS base submit editor to specify users, provide completion and selection dialog for them.

Fixes: Add a combo for diff file browsing, bring diff editors to front, exclude qconfig.pri from files examined by p4.

Details:  - It just doesn't work in Mac menus (at least not with Qt, but
I suspect it's some Mac thingy), so just don't do it.

    Details:  setCurrentEditor was sudddenly private

Details: Also remove unused change number dialog.

Many singletons have their own instance() method, in which case there is
no need to use ICore::instance() to get access to them.

replace ExtensionSystem::PluginManager::instance()->getObject<Core::ICore>() by Core::ICore::instance()

forward declaration is sufficient.

Details:  - Naming convention

Details:  - Conform to naming convention

Details:  - To make it conform to naming convention.
