rename SQLiteNG to SQLite and SQLite to SQLiteLegacy

this seems the least evil way forward since mono 2.6 and later will see increasing usage, and this only works with what was SQLiteNG
MAC USERS WILL NEED TO CHANGE REFERENCES TO "OpenSim.Data.SQLite.dll" to "OpenSim.Data.SQLiteLegacy.dll" in OpenSim.ini and config-include/StandaloneCommon.ini (if using standalone)
See the OpenSim.ini.example and StandaloneCommon.ini.example files for more details
This commit also temporarily changes unsigned ParentEstateID values in the OpenSim.Data.Tests to signed temporarily, since the new plugin enforces creation of signed fields in the database (which is what the SQL actually specifies).  And change data columns in sqlite is a pita.
