Implemented EZP-19411: Avoid file_exists and include calls for registering datatypes and workflows
Replace deprecated check for innodb support

Since MySQL 5.6.1, the server variable `have_innodb` has been removed. The command `SHOW ENGINES` instead is supported since MySQL 4.1.

See http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_have_innodb
