Enabled INSERT into 'schema.table'

I found that you guys added the ability to query a table from specific schema, but was missing the ability to insert. I assume update and delete are also missing, I will find out this week and add those as needed.

I was tempted to change `BasicInsertBuilder.buildInsert()` to use SQLBuilder, for consistency with `BasicInsertBuilder.buildInsert(Query)` but decided to make as minimal a change as possible.

I think these changes made are small enough to not cause any regression. All the `sbt test` passed successfully, I assume that that means it works for the embedded DBs you use for testing.
