Linux: Re-enable getprocesses, overlay, and keyboard watcher.

[TheGreatMcPain]

The overlay does work on Linux, but with some quirks (mainly on tiling window managers).
I still need to add the Linux specific fixes for the overlay, which consist of disabling hardware acceleration and adding a timeout during window creation..

Luckily the user can fully disable the overlay if they wish via BetterCrewLink's settings. (unlike the original version of CrewLink)

My fork of memoryjs does support getProcesses, so I've re-enabled that code too.

I also have a linux port of node-keyboard-watcher which works, but it's not cross-platform friendly yet.

I just added the fixes for getting the overlay to render properly.

Still doesn't work properly, because of electron not applying transparent visuals by default.
But it is easily fixable: In package.json script section for electron-webpack, you need to add this option: --enable-transparent-visuals.
Howewer, this commandline option for electron should be enabled only for linux platform i imagine

EDIT: the interface also crashes on some clickable elements with this error (doesn't happen on @TheGreatMcPain electron-overlay-window fork, only @OhMyGuus merged one):

/home/donokami/x/BetterCrewlink/node_modules/electron/dist/electron --inspect=5858 --enable-transparent-visuals /home/donokami/x/BetterCrewlink/dist/main/main.js: symbol lookup error: /home/donokami/x/BetterCrewlink/node_modules/electron-overlay-window/build/Release/overlay_window.node: undefined symbol: ow_stop

That's because I haven't updated this pull-request with the most recent changes to OhMyGuus's fork of electron-overlay-window.

Also when you say, "doesn't work properly", is the overlay not transparent, because it's transparent on my end.

It is fully white on my side, until I enable this --enable-transparent-visuals option. Howewer on my laptop I only have iGPU, no GPU, which could explain this difference

[TheGreatMcPain]

Okay, I will try it on my laptop which has an ivybridge intel iGPU.

Finally found time to make the Linux version fully happen +1, I remade the branch since it had a lot of stuff that wasn't needed like you mentioned and moved it to a temp fork so I can test the installation process before it gets fully merged to the main repo.
Will add u & everyone who made it possible as co-authored when I merge it 👍
