Version 5.1a
- added a 'tidy up' command with 3 options in the graph mode
- application cannot be exited by Ctrl+Esc. It is also properly locked in all dialogs
- bug fixed: history graphs for Net Value of accounts were not created automatically.

Version 5.1
- it is now possible to import historical quotes from a text file to fill history graphs (one share or several shares at once)
- the application is now more "pointer friendly" (tap a line to select a quote to update, to display the list of transactions on that share, to select a transaction to update,...)
- speed has been significantly improved (update of quotes, display of graphs,...), thanks to a change in the database structure
- a "lefthanded" screen option is now available (see Preferences)
- a "View" card has been added in the Graph menu: it is now possible to see up to 5 data series on one screen, and to compare "normalised" values (see "Index" in help)
