Phalanx B3+F2, Pure FR, Block changes

Had a hundred or so matches and figured a few of these changes were
needed.

Requested CVAR changes:
bb_kb_block from 1.3x to 1.2x

Phalanx:
F2t1 knockback scale 0.75->1.0
Not needed, just made gave less breathing room for opponents between F2
and F3

B3t1 knockback 1.3->1.2x
B3 knockback was too high, really safe on block and resets too easily

B3t2 locktime increased to 0.7
B3t3 locktime increased to 1.0
B3t2t3 do pretty good damage on rapier (20/40 respectively), it needed
more locktime to compensate.
Pure:
Fr locktime from 0.6->0.5, knockback from 0.5->1.5 (Looped into itself
on Jian, gave it more knockback to reset and less locktime to compensate

HRt3 animation reverted to HRt1's
Insane damage on scim, no time to tinker with that
