ProjectExplorer: Support bulk renamings in project tree

If a user changes the name of a file abc.cpp to def.cpp, and there is a
file abc.h in the same directory, it's likely that the user wants to
rename that file to def.h. Detect such circumstances and offer the user
to automatically rename the sibling files.
