SatellitesPlugin: write object type to catalogue
SatellitesPlugin: remove unused code
SatellitesPlugin: change default tab in config dialog
SatellitesPlugin: derive config model for earth and orbiter satellites
SatellitesPlugin: prepare for loading orbiter catalog files
SatellitesPlugin: fix typo
SatellitesPlugin: add setStateVector() method

 * Add a setStateVector() method to mex/planetarySats in order
   to set the state vector directly.
SatellitesPlugin: add download and parsing of catalog files

 * This adds downloading and parsing of data for planetary satellites.
SatellitesPlugin: clear satellites when switching planet
SatellitesPlugin: some minor code clean up

 * use startWith() instead of indexOf()
 * make sure, coordinates are not NaN
 * clear() satellite items only when switching the planet
 * fix: release planetarySats object
SatellitesPlugin: fix typo
SatellitesPlugin: remove obsolete comment
SatellitesPlugin: avoid 'using namespace'
SatellitesPlugin: use section() instead of mid(indexOf())
SatellitesPlugin: add support for ESA's TASC service

 * This adds support for ESA's TASC service (http://tasc.esa.int)
   to tools/gen-satellites-data.
SatellitesPlugin: add data interval options

 * Add data_from, data_until, data_for_day options to SpaceObject.
SatellitesPlugin: fix bug with setting current planet

 * While loading satellite items, the current planet's name has not
   been passed correctly to mex' setPlanet() method. This lead to
   wrong calculations for satellite positions and orbits.
SatellitesPlugin: increase number of orbit track points
SatellitesPlugin: apply upstream fix

 * This adds an upstream fix from Gerhard Holtkamp. It fixes
   a crash with orbital eccentricities > 1 in planetarySats.cpp.
SatellitesPlugin: prepare configuration for planetary satellites
