* Do not trust the client! ServerFont::GetEscapements() now takes a

parameter for the length of the arrays, so that even if the char/byte
  counts do not match, no memory is overwritten anymore.
  This fixes bug #1862; .canna obviously contains invalid UTF-8 
  characters, or there is a bug in StyledEdit (or deeper) and it doesn't 
  call BFont::GetEscapements() correctly.
* Fixed some cases of unchecked allocations in the font handling methods
  of ServerApp, added TODOs to all other ones.
* Improved error code when creating a window fails.
