porting scintilla to qt

# HFacer.py - regenerate the Scintilla.h and SciLexer.h files from the Scintilla.iface interface
# definition file.
# The header files are copied to a temporary file apart from the section between a //++Autogenerated
# comment and a //--Autogenerated comment which is generated by the printHFile and printLexHFile
# functions. After the temporary file is created, it is copied back to the original file name.
