Autowiki Stock Parts Template (#76765)

## About The Pull Request

Autowiki functionality for stock parts

stockparts.dm extends the autowiki datum, implementing multiple
functions to upload images of and parse information about all the
craftable stock parts in the game a player is likely to encounter.

The template can be called on the wiki by using
`{{Autowiki/Content/StockParts}}`

## Why It's Good For The Game

Better documentation means lower learning curve, items that are properly
up-to-date is a good start.
This will probably branch into a few other autowiki additions for the
other various items from research, has the potential to lead to a full
documentation of the autolathe if done correctly.
