Some updates to GLorp

[Mariano Martinez Peck]

Hi guys

I did a couple of things related to Glorp. I commited 2 fixes related to the connection pool.

Also, for the native postgres driver, I adapted the pool we have for OpenDBXDriver. It's quite ugly because we are duplicating quite a lot of code, but the hierarchy make things complicated here and I don't have more time to improve it (at least not right now). If someone wants to give it a shoot :) You can give it as an exercise to a student hahaha. 

So...to sum up, some fixes in GlorpOpenDBXDriver and the new connection pool to

GlorpDriverPostgreSQL.

Cheers,
