[Geany-devel] Improved syntax highlighting for Forth

[oco at newmail.ru]

Hello to all!
I really enjoy using Geany as an IDE for embedded programming. I often use Forth language but syntax highlighting for Forth in Geany recognizes only one "primary" keyword set.
So, this is a patch for adding "keyword","defword","preword1","preword2","string" keyword sets (as in Scintilla source)
