[Geany] Adding Syntax Highlighting for New FIletype Problem

[Jason Oster]

Scintilla needs to find the SCLEX_R lexer. Most of the default lexers  
are removed for Geany (scintilla/Lex*.cpp files) You should be able to  
download a copy of Scintilla 1.76 and copy the proper lexer file into  
Geany's scintilla dir. That should be the only thing left to do, if I  
recall...
