further improved file behavior

- added visible line angles when drawing

removed some debug code

- bumped max amount of recent files from 5 to 10

- added selection auto-subfiling(!)

- line lengths are now displayed when drawing

- non-release builds now display git revision info if available. This turned out to be much simpler to implement than I expected..
