[Libreoffice] first post and patch proposition (condfrmt)

Hello everybody,

It's my first post on this mailing list.
Until 3 years ago, I posted regulary on french ooo lists. I return on 
the french dev list but it's a nomanland ;-) only 3 messages !
I think everybody is coming on LibreOffice :-)

I find a hack I've created in 2008. Yesterday, I've worked to finalise 
it. I think it may interest you :
unlimited count of rules in conditional formating

I'm not qualified for making a patch. Please somebody can help me ?

Source code is here :

other languages; particulary for asiatic languages.
