Added new class RSTreeWidgetItem derived from QTreeWidgetItem for sorting strings case insensitive without proxy model.

Browse Source 
Sort strings case insensitive in NetworkDialog, PeersDialog (changed to RSTreeWidgetItem), MessengerWindow (changed to RSTreeWidgetItem) and SharedFilesDialog (with folders first).
Sort the columns size and age in SharedFilesDialog by internal data and not by the shown string.
Save and load layout of the SharedFilesDialog in profile.
