Minimal Stemmer for Portuguese

This follows the "RSLP-S" algorithm presented in:
A study on the Use of Stemming for Monolingual Ad-Hoc Portuguese
Information Retrieval (Orengo, et al)
which is just the plural reduction step of the RSLP
algorithm from A Stemming Algorithm for the Portuguese Language,
Orengo et al.
