SBGAT V1.05.2

• Adds SBGATObsRadar to SbgatCore, a class emulating range/range-rate radar measurements. The corresponding menu and action are also available in SbgatGui
• If gcc exists in Homebrew's Cellar, SBGAT and its dependencies will be compiled using this OpenMP compliant compiler, giving better performance on multithreaded platforms. This functionality had to be postponed due to Qt 5.10 incompability with recent gcc versions on MacOS.
