0.7.3
at splash screen it's shown conversion rate on update DB
new db: 0.57: 
-jump and jumpRj have angle
-events have simulated column. Also jumpRj and runInterval temp tables.
-simulated shown on treeviews and edit events
Upgraded Gtk.FileSelection (deprecated) to Gtk.FileChooserDialog (hope
this improves windows usability)
Code cleaning, improving:
-new code event.InsertAtDB
-start using sqlite classes as non static (done for createTable at all events)
-created SqliteJumpRj, SqliteRunInterval
-created method SliteMain.convertTable
removed crash test on menu
