Title: Since property pr

An initial draft for implementing a 'since' property for a DatabaseField column.
This implementation attempts to prevent erroneous raw sql statements in the onUpgrade of Android.

Would appreciate feedback and your thoughts on such a feature in ORMLite.

Things I came across:
* Do we only use ADD COLUMN or also implement RENAME?
* How do we deal with INDEX / PRIMARY KEY constraints?
