Add option to the Grails Builder to allow "non-interactive" to don't be added to the grails command

Currently the "non-interactive" option is always appended to the Grails command.

This setting should be optional.

Currently, if the "non-interactive" is appended to the end of a "grails schema-export", the file name generated will be "non-interactive"

A workaround would be to add the following command to the Grails Builder so that Bamboo can identify that it already exists and don't append it.

grails schema-export -non-interactive file_name
