Make sure that we have server side types for all meshes

This is an ongoing project to make sure all of the media in Ember is represented by server side types. Currently there's a lot of media which is never shown because there's not any corresponding server types. This needs to change so we better can show off all nice media in Ember.
The steps needed to be taken are:
1) Make sure that all (non-deprecated) meshes in the svn media repository are represented by a Ember Model.
2) Either by hand or through the Atlas type exporter create a corresponding .atlas type specification which matches the Model.
3) Install the .atlas type on the server, either by adding it to the already existing .atlas files found in the data directory of the cyphesis server, or by adding a new file.
4) Alter the http://git.worldforge.org/?p=ember.git;a=blob;f=src/components/ogre/modeldefinitions/modelmappings.modelmap.xml file in Ember to allow it to match the atlas type to the Model.
5) repeat until all meshes are used
