Rename the prop file inside MultiMap

[Philippe Pinard]

The prop file inside a MultiMap should not have the same filename as the MultiMap since this causes problem when the MultiMap is renamed by the user. The prop file should have a standard filename.

Patch to solve the problem.
The property file of the multimap is always saved under properties.prop

[RML00 (rml-image)]

It would be better to rename alias.prop to alias.properties and to fix the name of the MultiMap properties files to multimap.properties.

These modifications were done in RMLImage revno 1441. Need to apply the enclosed patch to EBSD-Image.
