Add queue system with background downloading and much more (#73)

* Do not build here until it is merged.

* WIP: Queue System.

Right now crashes randomly for whatever reason..

* Animate queue spinner more slowly

* Use LightLocks to prevent crashing in the queue

(I hope it's fixed at least)

* Build nightlies in queue-system

* Use version.h for version and specify 7 digits

* Remove unneeded $(CURDIR)

I put that these for testing, but it's not needed

* Multiple Changes, see desc for more.

1.) Theme Implementation.
2.) Show Battery + Time.
3.) Some more work on Queue-System (might still be broke).
4.) Update Copyright to 2021.
5.) Add `%FIRM%` to regex.
6.) Mass Add to Queue.
7.) Search with AND / OR filter.

* Gaaah, not again...

* Remove DoNothing, some LightLock changes, etc

aka
Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience.

* See desc for more.

- Current Queue Entry can now be canceled.
