Changelog:

• The minimum required Qt version is now 5.12.
• Experimental support for landscape orientation on Android (not enabled by default yet, see comment in GameViewMobile.qml).
• Fixed crash if application was closed while game analysis was running.
• Added missing include that broke the compilation with GCC 10 if compiled with PENTOBI_BUILD_GTP=1.
• Don't use Fusion style on desktop anymore because it is currently broken on some Linux distributions.

Depends on D8895
