#19 RDP keyboard layout support

[David Sommerseth]

I modified tsclient today to add keyboard layout settings. I did not check this tracker for other fixes until afterwards, which was kind of silly of me.

I found this one: https://sourceforge.net/tracker/?func=detail&aid=2777130&group_id=192483&atid=941576 ... However, that's a pretty massive change set with "no changes" (most probably white space stuff). The version I wrote is practically doing the same, but the patch is looking cleaner.

Feel free to reject this one if the other one is better.
