[FEATURE-REQUEST] Support for Repos using MySQL

[cybrox]

Describe the problem you're proposing to solve
When using Kaffy on a project with a repo using the MySQL database drivers, everything related to schemas breaks, as MySQL does not support ILIKE, only LIKE.

Describe the solution you'd like
Depending on the repository database driver, LIKE (MySQL) or ILIKE (PostgreSQL) should be used.

Describe alternatives you've considered
none

Additional context
I forked kaffy and did the change manually for testing in this commit and it works fine. ILIKE is only used in this one place.

I could submit a PR for a dynamic approach based on the repository driver but I think this would collide with #180. Guess it would be best to complete that PR first :)

+1 to this please

This prevents usage with SQLite3 as a DB too - admittedly this is a more esoteric crowd!
