Fix RAM problem

Garbage Collector of C# is too slow, so we have to force it after too many files and at the end.

Also show the version at the title.

Improved performance again

Everythings fasteeerr

Improved performance

Better performance, specially at bigger files.
Also the memory usage should be a bit lower now.

Fixed some things

The numbers should be more accurate now.

better function detection

function couldn't be detected when there were other chars than space, comma and next line.
Fixed it, now there are much more chars.

If there is something missing, please tell me (in Issues or with a pull request (funcs/Util.cs)).

Fixed comment bug

There was a bug, which couldn't really detect if something is in a single-line comment.
Also renamed the whole thing.

Rewritten - much faster!

The code got rewritten and is much faster than the previous code.

Tested:
Nearly 32x faster.

First version

Here is the first version.
Shows amount of LUA-files, other files, functions, lines, characters, comment-lines and comment-characters.
Whitespace isn't count as character or line.
