qt-creator/src/plugins/texteditor/texteditoractionhandler.cpp
Konstantin Tokarev 7ae82b9f94 Added TextEditor commands FollowSymbol and JumpToFile. 
Most of editors have "jump to file" or "follow symbol" actions. This
patch reduces amount of related boilerplate code.

New actions are made optional to prevent shortcut clash (both use F2).
