  Log Message:
  -----------
  Imagery: move signatures to subdirs (#1850)

Imagery: move signature files to a <name>/<element> type directory structure (a.k.a. _misc)

Full path to signature file now is:
location/mapset/signatures/<type>/<name>/<element>

This new structure will allow to store arbitrary number of files for each signature.
None of existing signature types utilizes the new functionality.
