Pull request in develop and regression suite (test013)

Basically there were three problems:

1. cpimport's data type matching couldn't find TEXT columns, caused a bad memory read and error
2. the conversion code for INSERT...SELECT to cpimport data had a bad field length calculation for 64KB BLOB/TEXT columns
3. the conversion code for INSERT...SELECT to cpimport data was doing a bad recursive insert for TEXT data

This patch resolves all 3.

NOTE: any TEXT columns created prior to this MCOL will break once this is merged. This is due to using a bad data type ID which subsequently caused problem 1 above.
