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.

- Fix installed list.

- Display Download Speed.

- BYE BYE Queue LightLock!

* Various adjustments to the queue menu

- Make cancel button slightly smaller
- Right align "Steps: ..." text
- Remove "Current Operation:" text
- Change KB/MB/GB to KiB/MiB/GiB
- Lots of little positioning tweaks
- Fix bug where you could get stuck in the prompt
- Make spinny thing have a ! when action is needed
- Make extracting file increment at the start instead of the end
- Delete dumb VS Code file and gitignore it
