Rangers card to replace Bones, fix save compat a bit

The skeletal warrior and bone dragon, while strong, had direct overlap
with Yred's gifts, while skeletons are hardly unique allies. Not that great
of a concern considering the different natures of support from permanent
and temporary allies, but still something that could be replaced with
something more distinct and unique for Nemelex.

This card summons a niche close to unused for player allies, in archers.
There are four tiers:
1: centaurs or yaktaurs
2: centaur warriors or fauns
3: yaktaur captains or naga sharpshooters
4: satyrs or merfolk javelineers or deep elf master archers.
With card power:
0: Two or three of tier 1.
1: One of tier 1, and either one of tier 3 or another tier 1 and one of tier 2.
2: One of tier 2, and either one of tier 4 or another tier 2 and one of tier 3.

Should be more interesting, and possibly marginally stronger if you need
more damage-inflicting and less damage soaking.

Also, avoid earlier Herd and Bones cards from screwing things up,
and stab at some errant tabs.
