Add title and description to nls for better internationalization

[bogibrynjar]

Currently the title and description of geoform is hard-coded in the details.js part of the code. Better internationalization would be easier to achieve by moving these elements into the resources.js file in the nls section. This would offer more flexibility and better support for multilingual deployments.

Also there are other labels/text in the defaults.js that should be moved to the nls/resources.js such as:

attachmentLabel
attachmentHelpText
submitButtonText
viewSubmissionsText

I would love to do this myself and contribute but not a developer unfortunately!
