[Devel] new PS parser

[Werner LEMBERG]

Dear all,


I've heavily modified the PS parser to handle comments and strings
properly.  Please test extensively!  Additionally, I've made MM
support work again which was broken due to a small omission.  I'm
especially interested whether the new routines slow down parsing
noticeably.

Still missing is using the new routines for Type 42 fonts.  Roberto,
can you send me a T42 font privately?  I don't have a single one...
