Library table: allow to ignore Track double-click

[ronso0]

Many times a accidental touchpad double-click has caused a PITA in live sessions because it cleared an already prepared deck.
Setting track double-click to "AutoDJ add ..." would protect the decks but pollute the AutoDJ queue.

So I'm adding the valid 'Ignore' option here. Default is untouched (load to deck).

Also the options section is renamed: Track Load Action >> Track Double Click Action (as the labels extracomment="" already says)

LGTM thank you. Waiting for CI.

@Holzhaus: unfortunately the pre-commit hock on GitHub fails. Can we revive the Travis one
and keep both of them until GitHub is stable?

I also cannot get used to the cluttered output of the GitHub version. The original text only output is much more informative at once.
Can we implement this at GitHub as well and bypass all the fancy GUI menüs?

The failure was caused by an in-progress apt mirror sync while installing clang-format. That would have happened on Travis as well. I restarted the jobs and now it works:

Hmm, I like it actually. The Travis Website became quite slow when showing the huge log. For a text only output, just click the hamburger menu in the top right corner and select "View Raw log"

Unfortunatly MSVC fails with

set to Draft because I overlooked that this change is also suppressing [Library],GoToItem in the tracks table.

wrong.
It was just that GoToItem wasn't working earlier.
I included the fix from #3196 here.

@daschuer Please check again.
