Changes that check for a weird condition that was causing cards to get corrupted.
A similar change has been applied also to /gamma (in a different commit, though)
The javascript was checking for the parameters assuming the backend
provided version information. The community edition backend does not
supply any versioning information so the javascript checks both
locations
Fixed PHP backend and /beta code to handle request and data format compatible with /gamma.
At the moment adding/deleting/editing records seem to work fine.
