<!-- Write **BELOW** The Headers and **ABOVE** The comments else it may
not be viewable. -->
<!-- You can view Contributing.MD for a detailed description of the pull
request process. -->

## About The Pull Request
re-implements #1716 as a base and adds cutter functionality to plasma
cutters
also implements and uses gear packs from #2103 that never got in.
makes plasma cutters unable to mine, shorter range, and do burn instead
of brute.
angle grinders are integrated into grinder packs, like water backtanks.
Also draws power from a cell.
jackhammers can no longer break down walls and girders.
### Cutters can currently deconstruct:
- girders
- walls
- reinforced walls
- airlocks
- airlock frames
- grilles
- machine frames
- computer frames
- catwalks
- chairs
- beds
- tables
- lockers & crates
- salvage machines (the wasteplanet ones)
- railings
- lattice
- wooden barricades

cutters can also cut open safes and locked lockers & crates

attempted to revert map changes but using git checkout doesn't
completely revert the gecko. Will try again later.

adds a mech salvage saw and a prototype energy saw. Doesn't make either
available yet.

<!-- Describe The Pull Request. Please be sure every change is
documented or this can delay review and even discourage maintainers from
merging your PR! -->

## Why It's Good For The Game
Jackhammers as a main salvage tool is dumb, and angle grinders and
cutters make more sense and have better functionality. Cutting apart old
ruins and ships should be a reasonable source of material and shouldn't
take years.
<!-- Please add a short description of why you think these changes would
benefit the game. If you can't justify it in words, it might not be
worth adding. -->

## Changelog



:cl:
add: angle grinders for salvage
add: reworks plasma cutters for salvage
/:cl:

<!-- Both :cl:'s are required for the changelog to work! You can put
your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
