Title: [DB2] Fix add and remove column for ActiveRecord 4

Hi,

I fixed two bugs with DB2 adapter.

In ActiveRecord 4 the method remove_column has changed. This commit fix a bug with migration reversion.

I also changed add_column method. The new implementation permits usage of reserved words for column names.
