conflict resolution file format proposal

[vm-wylbur]

When there are sync conflicts, the user will have to choose one file from local, synced, or remote. This is the version of the file that will be retained, the others will be overwritten. In the case of sxLCR__C_ne_R, the user can choose delete. Thoughts?
