Support for setting collation/charset at the schema level.
Porting of non-running migration test to new test running layout.
Resolves issue #19. Resolves issue #28. Resolves issue #17.
Should allow for changing the types for particular columns (Int, SmallInt, BigInt, Text, Char, Float, etc.).
This seems to work with the current migration test, however use of floats and such in model instances has not been heavily tested.
Likewise, in porting migration the full suite of index migration tests has yet to be ported.
Likewise, issue with dropping columns from a model persists and seems related to `defineProperty` in JDB core choking when used to try and undefine.
