Instead of saving everything in MainApp::saveStateSlot, save each object
separately. As a result, this will save a lot of writes to disk.
Other changes includes:
Saving bookmarks also in private mode. Closes#1208
Cleanup of code
Code was formatted with patched astyle that correctly formats
foreach macro.
Normalize tool is now used to normalize all signal/slots signatures
to normalized format. It saves few reallocations on connections.
