Added everything.

Quick hotfix to remove the music from playing when it's a calm tarr.

Added some new things:
- Slimpedia entry for the Calmed Tarr
- Tarr Plushie
- silenced a minor spelling mistake

- Balance changes (except more like I added any balance at all - the calmed tarr will now abide by the rules of hunger).
- Made some progress on the rainbow slimes.

Overhauled Tarr Plushies.

Cleaned up the icons a bit, doing things like
- moving an icon's background a few pixels to the left

All kinds of pumps can now collect slimy solution, though it's very rare for the non-abyssal pumps.

Added slimy solution Slimepedia entry.

Modified slimy solution icon.

Modified calmed tarr Slimepedia entry.

Increased the tarr's drive to eat the slimy solution. Hopefully this helps people who can't get the tarr to eat it to eat it.

Did some patch work and the tarr now should eat the slimy solution. Hopefully.

Quick fix relating to slimy solution.
