Sqlite's lack of an 'ALTER TABLE CHANGE' statement has prevented echo from
supporting sqlite, and by relation has prevented Echo's unit tests from
running within the foundations jenkins CI environment. This patch detects
if the database is currently an sqlite database and applies a specially
formulated patch that performs a rename/copy/delete operation to get
the equivilient of an 'ALTER TABLE CHANGE' command. Additionally renames
one index to have a more unique echo-specific name.
