Hi,

Sdl2Gui works but the key handling has some problems:

1) Unicode characters are sent as characters twice (e.g.'ş' character (s with cedilla) will be printed as 'şş'), because fbKEYtoK function does not shift (+K_DELTA) the characters that are not in the key map. (In keydown/up events)
2) Backspace is not handled correctly.
3) Numpad "Enter" key is not implemented.
4) Cosmetics issue: The keymap is somewhat awkward. It has the value-key order instead of key-value order.
5) tab, return and space characters are handled in the fbKEYtoK function, not via the map. (What is the rationale for this behavior?)

This patch aims to "fix" these issues.

Note on 4: I reversed the order of map, and moved it to a VectorMap.

Please review.

Best regards,
Oblivion
