Merge pull request #60 from purohit/master

Adds support for SAVEPOINT, ROLLBACK TO SAVEPOINT, and RELEASE SAVEPOINT
Add support for time.Time objects to gorp.

This commit adds support for storing and retriving time.Time objects,
by passing through such objects to the underlying driver.  This
resolves gorp issue #14.

The commit is tested and works with the github.com/mattn/go-sqlite3
driver.

The commit does not currently work with the
github.com/ziutek/mymysql/godrv driver, due to a bug in the mysql
driver.  This problem is resolved by mymysql pull request #77.  I have
successfully tested that with the fix from pull request #77 applied to
mymysql, and with the current commit applied, gorp can correctly store
and retrieve time.Time objects from mysql databases.

This commit is NOT tested with the github.com/lib/pq driver.
Doc fixes.

This commit contains fixes to doc strings, both to make the
documentation on godoc.org look nicer, and to follow the rule that the
documentation for a method should start with the method name.

The commit does not change any of the Go code itself.
Use fmt.Errorf(...) instead of errors.New(fmt.Sprintf(...)).
Fix another line which godoc.org mistook for a heading.
