Remove armor from talisman options

After some 10-year old ick-ocking pubbie edgelord has shown us how good
of an idea this is, I have decided to remove armor options from the
talisman (starting and possibly imbued). Here's my reasoning :

- A rune already exists, and you can imbue it, so you sure as hell
aren't forbidden from having those edgy rune robes
- Giving someone the ability to muderbone with gear that OPENLY screams
what's happening, in a STEALTH GAMEMODE, is one of those good /tg/ ideas
that plague our code
- Seriously, you have three words to research. Hell is usually supplied,
then find Destroy and Other. You sure as hell shouldn't be able to
summon armor if you wouldn't even be able to make a rune if it raped
your mind
- Sides effects include not being able to imbue armor talismans anymore,
but if you have tome and a few seconds you can make armor anyways
