If there was a reason for these to be so weak I can't find it.  Things without gear scale very very badly.

Minor bug fixes and typos

Mostly fixes for various typos and grammatical errors, but also has a few small bug fixes:

-"of mastery" and "of perfection" amulets now check for conflicts between amulet power source and the category boosted

-Dwarf's Stone Walking racial is no longer usable to target an empty space and move one tile

-Added a long_desc to the stun effect noggin knocker gives to prevent an error when the player is hit by it

Isn't Vim a text editor too?  I feel like this resource is some sort of political statement

These are really weak and don't have much meaningful differentiation from jellies/slimes/plants anyway.  Lets just phase these out faster for lack of a better idea.

- Remove damage penalties and talent level caps

- Fix autolevel_scheme

- Damage reductions removed

- Convert damage percent to 100% from 50%.  Its hard to even notice these are strongly elemental themed with 50% given how spammy the log gets, and this gives them a unique niche.

- Remove some talent level caps

The old version was messy and had a lot of little numbers for no real reason.  This one is cleaner and reinforces Reaver as a melee class.

- Stacks up to 10 times

- Now only stacks on melee attacks with no turn limit.  So Bone Grab+2 melee spells fully stacks it.

- No longer decays slowly

- Duration set to 3

- Can now be targeted through allies (Rot worms, etc)

- Now checks Teleport resistance

- Always moves the target to the closest space adjacent to you

Immobile melee stuff is really prone to getting stuck with a target it can't reach.  This is mostly relevant to melee Player pets.

- No more ability refund.  This often failed due to projection sources being messy (especially for melee) and punished you for letting things like disease get the kill.

- Vim regeneration on any kill scales faster with Willpower and now also scales with target rank.

- Bloodcasting is now baselined in the resource allowing you to pay Vim costs with 200% of the cost as life.  This does not let you use die_at.

- Vim value is now shown on Actor tooltips
