This commit contains the following things (this is NOT the magic update):

Browse source 
* Optimization. Very subtiles optimizations has been applied to the code.
* Id mime parsing. Detects cid: objects.
* Debugging removed. All if $debug code has been removed. (Debug code is
  not supposed to be in stable releases).
* Indentation and space tab.
