feat(mining): automatically mine new blocks

[Jhoyola]

Closes #566

Based on the code of @zackypick
Continues the unmerged PR #613

Description

Added auto mine dropdown button with several options (Off, every 30s, every 1m / 5m / 10m)
Button includes embedded progress bar (time left to mine)

Steps to Test

1. Click the new toolbar button for options
2. Select any of the interval options
3. Auto mine will start according to interval
4. Verify that the blockheight changes when the progress bar goes to zero
5. Change the interval on the fly, and verify, that the mining still works
6. Select Off to turn down automine

Thanks for taking over this PR.

I tested it and the functionality works as expected. This seems pretty much done. I just left a couple of minor tweaks.

It looks like the unit tests are failing. Would you mind taking a look at them.

Yes, I'll see if I can fix them

[Jhoyola]

Fixed the tests and added some new unit tests for the automine.

[Jhoyola]

I will still edit the tests a bit to get the coverage to 100 so CI passes fully.

[Jhoyola]

Sorry, didn't run the full CI before the last commit. Now it should be ok.
