Gmap Marker Regen

Gmap module uses a non standard way of storing the file id. It creates a managed file record. However, there are no file usages written to the file_usages table. During garbage collection files in public://js/ are deleted. The logic in Gmap module core looks to see if the variable gmap_marker_file is set. If so, it proceeds without if the file has been generated in the past AND if it still exists.
