Bumped release version to 1.4.2

- compiled successfully on win32 using mingw (makefile updated)
- updated LICENSE file to add copyright through to 2015 (I'm lazy!)
- my1console should now display ALT+Fn keys (NOT tested)
How could I got this wrong before...?
Minor edit

- keymap last tested on my laptop (different from std keyboard?)
- should check it out... but probably would not :p
