Help git by converting C# sources from UTF16-LE to UTF8

Hi guys.

I just noticed, that github (as well as my local git) were not able to produce a proper diff of phogue's latest commit.
As you can see in https://github.com/Myrcon/Procon-1/commit/632b0d3c80fa7f63017ff9ee5deb756404d3bf81
those files are treated as "binary" because the are UTF16-LE encoded and (even worse) contain a leading 2-Byte BOM.

So I took the liberty and converted all those *.cs below src/ into proper UTF8.
This pull request still shows them as binary, but as soon as the next commit happens, a proper diff will be shown.

Cheers
