This release adds last.fm support as well as the option to search for process names instead of window titles.
Spotify also now has the option to use your own api keys to prevent timeouts that happen due to rate limits.
Other than that there's some small fixes and interface restructuring.
Also there's now an installer for all three platforms, although I have to emphasize, that I have decided to
not offer any support for macOS anymore, there's still builds for it but any issues that arise are highly
likely to be not addressed, at least not by me.
This is also currently marked as a pre-release so I can get some feedback and possibly release a patch for bug fixes.
