Adding translation capabilities to the system is taking shape. Saving and approval as well as most general locations should be done. Also fixed some errors in general save and approve methodologies.
Errors from language support are fixed. Language support should function but needs lots of testing and UI support. Fixed some inconcistencies in StudyVariable handling and parsing as well as included better knowledge when variable parsing has made changes that need committing to database.
