More work on the BFont special functions.

Browse Source 
* Reworked functions like GetEscapements(), GetBoundingBoxesAsString() and GetGlyphShapes() completely
* Made the ServerFont functions uniform in their prototypes and cleaned out unnecessary arguments
* Added new UTF8 handling functions to moreUTF8.h that are now used by ServerFont
* Put the common transformations of the FT_Face into an own GetTransformedFace() to lessen code duplication

In other words, ServerFont is now cleaned and handles UTF8 pretty efficiently. Some ToDo's are still left though.
