Tamil stemming algorithm

Hi,
I have added a patch for an affix stripping stemming algorithm for Tamil. This work was done as part of my Master's project. It has been sometime since I worked on this but I thought it might be useful for others. In case this does not satisfy the requirements to get included I will be happy if my repo can be mentioned in your documentation as an unsupported algorithm :)

Thanks
Damu
