if you have columns in MySQL that needs you to enclose their names in the create table statement, they are not properly enclosed in the migrate command.
CREATE TABLE test (`val:ue` INT);
will generate a changeLog-entry like this:
<column name="`val:ue`" type="INT" />
which will generate a create-Table statement like this on migrate-command:
CREATE TABLE test (val:ue INT);
which is not valid because the : is a special symbol and therefore not implicit part of the column name. A column name "val:ue" is allowed by MySQL but only able to be used correct enclosed by MySQLs column enclosings (`). I think it's not only on special chars but also on some reserved words that MySQL could mistake in the command. Anyway it seems important to enclose those.
