re-implements shiptest-ss13#1716 as a base and adds cutter functionality to plasma
cutters
also implements and uses gear packs from shiptest-ss13#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.
- 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! -->
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. -->

<!-- You can use multiple of the same prefix (they're only used for the
