- made sure that if the big mouse cursor is selected, the utility geometry in Excellon Editor has a thicker line width (2 pixels now) so it is visible over the geometry of the mouse cursor
- added posibility of using a big mouse cursor or a small mouse cursor. The big mouse cursor is made from 2 infinite lines. This was implemented for both graphic engines
- added ability to change the cursor size when the small mouse cursor is selected in Preferences -> General
- legacy graphic engine - made the key events work (simple or with modifiers)
- legacy graphic engine - made the mouse cursor work (enabled/disabled, position report); snapping is not moving the cursor yet
- solved issue #292 where a new geometry renamed with many underscores failed to store the name in a saved project
- the name for the saved projects are updated to the current time and not to the time of the app startup
- some PEP8 changes related to comments starting with only one '#' symbol
- Gerber Editor: finished the Copy, Aperture Add, Buffer, Scale, Move including the Utility geometry
- Trying to fix bug in Measurement Tool: the mouse events don't disconnect
