Will eventually replace file-control.php. Carries out same file checks etc, plus defines error info, form looparound system gone in place of 2nd XHR call on save as/new file save. All JS moved into a doNext string to be run on success (no errors). The only output here is the JSON response once we have carried out our processes. Note: Diff loading/MDT mismatch system not done yet.
