Multi-lingual support added

Well i should have thought about this more at the start of the application, but since Messenger Plus has a very wide user base spanning multiple countries and many languages i thought i should add support for different languages to the designer.

Next on the list is Create/repackage script functions and then a much needed code tidy up. Hopefully shouldn't take more than a week, starting a new job this week so I'm not sure what my shifts are going to be like yet.
