Update the CUBRID support:

Add a change_col method to DBIEngine.pm with a default of "change".
Changes in cubrid.pm:
No need to check for 'sqitch_db', defaults to project name.
Override the 'change_col' method to return 'changes_name'.
Quote tags in '_log_tags_param' and in the related methods.
Remove '_cid_head' method override.
Replace 'change_name' with the value returned by the 'change_col' method.
Fix: replace 'sqlite3' with 'csql' in '_spool' method.
Fix '--input-file' parameter in 'run_file' method.
The 'log' command is working.
