Based on OBS plugin template build scripts with some minor adjustments:
* Adjust format check scripts to exclude ./deps folder
* Adjust release scripts to only draft releases
* Always build installers
* Always upload build artefacts
* Build opencv for Mac and Windows releases
This should avoid issues of the whole plugin not loading if OpenCV is
not available.
This approach should also work for possible future external
dependencies.
Some mistakes found when packaging for Debian:
- Remove trash from rules and enforce hardening.
- Use the same licensing from Debian package to avoid a misinterpretation
from FTP Master.
- Fix target variable in debian/rules
* adapt UI for i18n
* add placeWidgets() helper function to ease translation
* add hint about Transition Matrix plugin on Transition tab
* translate
* rework UI of file tab
* write status of plugin to scene info file
* fix MacOS CI issues due to QT deps
* adjust to new name of deps archive
* use MACOS_DEPS_VERSION instead of OSX_DEPS_VERSION
* disable python dependency during build
