Port Porterstemmer module to 5.0 RC1

Hi,
Sorry I´ve posted it here, but, no 5.0 RC1 Version is for the module and I can´t select it for the issue posting.

I've tested Porterstemmer module in 5.0 RC1 and checked what to do for a module porting.
Module is working fine and as expected in 5.0 RC1 and as far as I could see, nothing else is needed to port the module to RC1, except the info file.

Please find it attached.

Regards,
Gustavo
