fixed: keyboard layout blank and double QWERTY entry

Since https://github.com/xbmc/xbmc/commit/c68e02a65f644da60d4aeba9091532bc83746c30 there is now a blank entry and a double qwerty entry, because the default fonts dont have these language character support.

There are 3 solutions to this issue

1) @notspiff fix to use a fallback to English with the font13 which is
not what's used in this part of skin.

2) use the modified Roboto fonts I was working on and no longer am, but already has
the Hebrew characters added (correctly or incorrectly idk) /me shrugs.

3) simple, use English names, since default language is English, users
must have some degree of understanding of that and smart enough to know it.

Since I no longer work on that font , nor speak such languages I was
adding characters for and have no desire to extend it from what is done
atm

so 3) This was my solution, both simplest and avoids dealing with niggling issues.
