OM Writer: Removed debug output
OM Writer/Reader: Added support for (re)storing properties of type vector
OM Reader: Properties can now be restored from files without the need to create the properties beforehand. Custom types need to be registered for this to work using the OM_REGISTER_PROPERTY_TYPE macro.
+PLY writer: Added option to choose if we want to write texture coordinates as uv or ply
