Add initial support for capacitors and commodities
Further simplify the modifying code
Deduplicate code
Add support to modify commodities
Properly assign commodities relationships
Move name, description and classification to new parent class DescribedEntity

Also make some other classes in the model hierarchie abstract
Add ECM model
Add Station.getQualifiedName()

A station might not have a faction (e.g. Amananth) so wrap that code
If an exception occured (e.g. null em) an exception in the finally block hides that exception
Allow creation of stations without a faction
Make Stations and Factions comparable
Use central component for rendering

Might be better to use a JSP-fragment for that, but for now this works better than before
Allow editing of ECMs
