Add create parts console

*Editing parts doesn't work (No buttons for it anyway)
*Removing items from the kit builder doesn't work (will be fixed in a later branch)

Everything else should work

a few other things are also in this branch
*Modified tag JSON so that finding the associated projects is done on the backend. saves a boatload of GETs
*In a prev branch forgot to update the confirm_identity console. That has been fixed
*Probably something else, I don't know. I'm tired.

@brotatos please give a good look over esp the python
