ClassView: Fix a crash when switching sessions

Move a code that operates on QIcon instances out from non-GUI
thread into GUI thread. Instead of storing the QIcon directly
inside ParserTreeItem, store the path to the project. Set the
real icon when we are back on the main thread side.

Rename some fields to start with m_ prefix.
