[WIP] Touch support

[chayleaf]

See #122

This implements touch support in the following way:

• Holding the screen and moving your finger up/down scrolls down/up. Scroll speed is hardcoded, and the mouse position is set to the initial tap position.
• A short tap emulates a return button press.
• A long tap that didn't move far enough to scroll emulates an escape button press (ideally, -click-to-exit would work, then this would be unnecessary) This is obviously not ideal, so I'd like some feedback on how a proper implementation should look like

Maybe programmable gesture support should be added? this would be useful for e.g. mode switching. I have no idea how the config for that should look though.

Moving discussion from #156 here, and will close according to authors responses.

@chayleaf, do you plan continuing work on this? I figured your PR was exactly that, a request to pull this into code base, and @lbonn has already expressed he would merge as an initial iteration.

Though it was not clear from this thread that this does not work as you state in 156... yes it's not perfect, but from my initial testing on two devices suffices to avoid having to replace rofi. There are some minor bugs, but at least it's functional and for me it greatly helps. Better this than having to look for another launcher.

If you can provide some feedback, I'm happy to help, or close the other PR -- just let me know :)

PS: duly noted regarding history/authorship, will do, thanks.

I am daily driving this branch on my phone, which is why I know it's not ready to merge yet. I do want to fix the issues when I have the time.

There is a reason this is a draft PR, draft PRs aren't ready for merging

For now, I recommend you to apply these patches locally.
