On several Linux version (Mint 18 for example) the package libavcodec-ffmpeg56 is replaced by libavcodec-ffmpeg-extra56.
To increase the compatibility I added an exception which define a conditional dependency between these two packages.
- Qt plugins and libraries (and associated files) bundled only if necessary
- Dependencies corrected (for Ubuntu 14.04 and 16.04, at least),
mostly manually for now
- run.sh sets Qt plugin path environment variable (=> qt.conf
no longer needed; removed)
- Fixed permissions of qt libs and plugins
- Added some missing plugins (and maybe a couple too many)
- Dependency list is built automatically, while excluding qt libs
