Create Formicid species and monsters.

Tavern post:
https://crawl.develz.org/tavern/viewtopic.php?f=8&t=8298

Wierdness & mutations:
- poison weakness
- retractable antennae (can wear headgear and ignore mutation)
- chitin skin (+3 AC)
- most weapons 1-handed, big weapons 2-handed
- permanent stasis
- ability to shaft self
- ability to dig
- Starts with 2 curing pots

3 monster versions of formicids were added:
formicid, a weak fighter
formicid drone, a stronger fighter
formicid venom mage, a magician with olgreb's and mass cure poison

[ Pushing to a branch for experimental playtesting on CSZO.
  Also optimised the new tiles. -nfm ]
