160055 – [PATCH] games/anki: eliminate py-pysqlite2x dependency

no flags

- bump USE_PYTHON to 2.5+ (the point is to not depend on python24)
- since it now requires 2.5+ use databases/py-sqlite3 
  instead of databases/py-pysqlite2x
- while here use GOOGLE_CODE instead of ${MASTER_SITE_GOOGLE_CODE}
- bump port revision because of dependencies change

I checked the code. They use this pattern when using sqlite binding:

 18 try:
 19     from pysqlite2 import dbapi2 as sqlite
 20 except ImportError:
 21     try:
 22         from sqlite3 import dbapi2 as sqlite
 23     except:
 24         raise Exception("Please install pysqlite2 or python2.5")

So nothing will be broken with sqlite3.

Fix: Patch attached with submission follows:
