[fpc-pascal] RTF backend for FPDoc.

[Michael Van Canneyt]

Hi,

I've committed an initial implementation for an RTF backend for 
FPDoc (implemented by Luk Vandelaer). I'd appreciate it if people 
could test it. It's selected with the --format=rtf option.

Currently one addition is still planned (other than fixing bugs): 
inserting an arbitrary piece of RTF at the front and at the end 
of the generated document.

The generated RTF is linear, i.e. it is suitable for printing. 
In order to create a .hlp file or a .chm file, some changes will
be necessary. (.hlp requires insertion of well-formed footnotes)

Please test it and report bugs as you can... (to me or in Mantis)

Enjoy,

Michael.
