Develop 4 r10backendfixes

Hi Greg,

This pull request is for all the changes and bug fixes I have made in the region10 repo which includes fixes to skubundles and fixing and cleaning up editing the event schedule. I have also added some bi-directional helper methods and a minor bugfix i discovered while testing. Also includes enhancements to ajax request/response.

Please merge these in when you get a chance.

Thanks
