Added CxxScanner class (with the ability to understand basic #ifdef / #if conditions)
Unlike other scanners in codelite source code base, this one is thread safe
New: integrated new CxxLexer code to parse and collect macros based on the current project settings + the compiler builtin macros
Removed the no longer executable codelite-clang (replaced with the new in-house CxxLexer library)
MemCheck: Avoid a Gtk-CRITICAL message on start-up by setting a minimum pane size in the Suppressions pane
Further optimized the old/new "pre-processor dimming" feature
Update the pre-processor dimming after the 'Global Editor Preferences' dialog has been dismissed
Remove the temp file generated to obtain the compiler builtin macros
Performance improvement to the cxx pre-processor
Define YY_FATAL_ERROR as an empty macro ( to avoid exiting ... )
