John Willard 9bf96c7763 Misc PDA code improvements (#70555)
* How to conflict with PRs: A guide

* Removes unnecessary support for the now-removed job disks from Tablet's TGUI menu, and tablet's ui_act.
* Adds autodoc comments to computer files
* Removes the unused 'unsendable' var on computer files
* Generally improves code on tablets, now process isn't looping through every idle thread twice!
* Moves the check for program in idle_threads above checking if supported by hardware, because it's already running, so there's no need to check.

* eh

* revert a scipaper change
