Add QMediaPlayer internal player back end (Qt5 only) * add config and GUI support for internal player back end switching; * make FFmpeg player disabling option consistent with other similar qmake options by using CONFIG; * add a new qmake option that disables Qt Multimedia player. This is useful for GNU/Linux distributions where Qt WebKit and Qt Multimedia packages depend on different GStreamer versions and don't work correctly when combined in one application. The existing FFmpeg+libao internal player back end has a relatively low-level implementation, which is difficult to understand and improve. There are at least 3 open internal player issues: 1) many GNU/Linux users have to edit their libao configuration file to make Goldendict's internal player work (issue #412); 2) libao's pulseaudio plugin does not support 32-bit audio, which means that many MediaWiki pronunciations don't work with the most popular GNU/Linux audio driver (issue #949); 3) Ffmpeg::DecoderContext uses deprecated FFmpeg APIs, which causes compiler warnings and means that this internal player back end may not compile with a future FFmpeg library version (issue #978). The Qt Multimedia back end implementation uses the highest-level Qt audio API and is very simple. This new back end works flawlessly on my GNU/Linux machine. I'm not making it the default back end because I don't know how well it will work on other platforms with different configurations.
