Change logic for formatted string in convertors

[DimitarCC]

This is because of remarks of @Taapat ....

Now you can define in the skin with whatever case you want and that will work.
Also spaces can be configured in the skin as well now.

Why not force the complete thing to upper instead do it label by label

[DimitarCC]

I cant force it to upper because of the separator string and normal types that was used before. If i force type to be uppercase the normal
<convert type="ServiceName">Reference</convert>
not going to work anymore.

P.S. i was thinking for even more flexible way to define that string format....
I will prepare another pull for discussion....
