Robot_module and cyborg stack refactor (#13527)

* robot_module refactor

* some fixes

1. adds medical stacks of 25 for the syndi medical borg
2. fixes various construction steps that weren't using `use()` or `get_amount()`

* review tweaks + other stuff

1. Makes a bunch of for loops into istypeless loops
2. Adds a readout of the current out of stacks a borg has, in the status panel
3. Slightly reorganizes the medical, syndi medical, engineering and syndi engineering cyborgs items

* fixes after upstream merge

* blank line for travis

* fixes and improvements

1. Fixed welder icon's not updating periodically if you were charging in a borg recharger
2. Fixes solar panels dropping /cyborg type glass when they were deconstructed.
3. Band-aid fix (incase #2 doesn't fix this) for cyborg stack's `source` var being null which resulted in tons of "cannot read null.energy" runtimes

* more fixes + constructable frame runtime fix

* removes toy sword placeholder

remove comment

* remove these as well

* .amount to .get_amount(), really should have done this before

* refactors robot_upgrades to work with the new system

- more cleanup
- adds documentation
- fixed a bug I made where you could delete your robot stack via crafting

* moves some unemag logic to the module file, makes more loops typless

* farie review

* fox review

* affected review and more TM bugfixes

* fixes comment
