top: Desklet that displays information from the top command

[RyanNerd]

Runs the top command every 5 seconds and displays the result in nice desklet grids
See README.md for the TODOs

Hi Ryan, sorry for the delay. I added this to the desktop on Cinnamon git (3.8) and it wouldn't launch, probably because Cinnamon now uses strict mode.

You can test this way by adding

'use strict';

at the top of extension.js.

@jaszhix I've added the 'use strict'; to desklet.js hopefully this fixes it. I'm running Mint 18.2 which is using version 3.6.7 of Cinnamon. I don't have the time to fork Cinnamon and attempt a build of 3.8 to test this desklet. Hopefully this small change will get the desklet to work. Thanks.

@RyanNerd No, Cinnamon 3.8 already prepends all xlets with 'use strict;' before adding them, adding that just lets you see where its having issues on 3.6. Do you see any stack traces in ~/.xsession-errors or ~/.cinnamon/glass.log? The desklet does load - which I didn't notice the first time - but its showing 0 for all RAM values because of this error:

@jaszhix The desklet on my machine has non-zeros for Ram (below)
.session-errors indicated one error -- which is now fixed -- please try again -- but I think it is unrelated to top.ram.total as it was an undefined variable of this.deskletId

What version of top is running on Cinnamon 3.6 (perhaps this is a parsing issue). top for me is version 3.3.10

glass.log

I'm using 3.3.12. I think this is just a TypeError, and not necessarily strict mode if you still can't reproduce. I suggested adding it in there to help you debug it without using 3.8, but its likely also has to do with 3.8 using mozjs52, where as 3.6 is on mozjs38. I also didn't catch the compatible version array in metadata.json the first time, wasn't prompted with the usual incompatible notice.
