Fixes several files incorrectly stated a different license from the actual project, as well as the copyright headers included in all files. This change has no effect on the licensing terms, it should clear up a bit of confusion by contributors. Plus the files get a bit smaller, and we have less duplicated information across the entire project.
Overall the project is GPLv2 if not built with Qt, and GPLv3 if it is built with Qt. There are no parts licensed under a different license, all have been adapted from other compatible licenses into GPLv2 or GPLv3.
Qt defaults to give every QAction a TextHeuristicRole, which means that certain key words will cause Qt to change how the QAction behaves. We do not want this, so we explicitly assign it to have NoRole instead.
Fixes#323
Instead of adding ourselves as the last entry which seems to confuse the MacOS Qt implementation, we instead insert ourselves before the Help menu. This should hopefully prevent the StreamFX menu from overriding the OBS About entry.
Fixes#323
Implements a manual and automatic update checker with support for both release and testing update channels, allowing users to stay as up to date as possible. It is fully compliant with privacy regulations around the world, as it stays completely silent and inactive until the user gives the Ok to connect to GitHub for the latest releases.
Moves the menu for StreamFX to the primary menu, so that it is not hidden under tools. This makes it clearer to the user if their installation of StreamFX is working correctly, in addition to reducing the steps necessary to use the menu.
Also the 'About StreamFX' dialog now actually shows up for every update, as expected.
Q_INIT_RESOURCE and Q_CLEANUP_RESOURCE can't be called from within a namespace and instead have to be in outside of the namespace, so by moving them into small inline functions we can fulfill this restriction.

Implements support for various new UI features that weren't possible up until now, such as an 'About StreamFX' window with a thank you to everyone that supported the project up until now.
