### Bug Fixes
- controller image fetch crash 
- `getDistanceTo()` with star group object, `goToObject()` with no angle 
- `setSimulationTime()` crash 
- move wikiname to celestial body, remove unused parameters, prepare star to be loaded directly 
- use proper values for depth test 
- post-process bugs (sorting, etc.) 
- check the wrong catalog type `catalog-lod`
- use local descriptors when server descriptor fails to recognize a catalog 
- button sizes adapt to content (fixes [#353](https://gitlab.com/langurmonkey/gaiasky/issues/353)) [#353](https://gitlab.com/langurmonkey/gaiasky/issues/353) 
- bug introduced in 40b99a2 - star cores not applied alpha - fixes [#352](https://gitlab.com/langurmonkey/gaiasky/issues/352) [#352](https://gitlab.com/langurmonkey/gaiasky/issues/352) 
- move temp folder into data folder - partially fixes [#350](https://gitlab.com/langurmonkey/gaiasky/issues/350) [#350](https://gitlab.com/langurmonkey/gaiasky/issues/350)
