Woo other char's blockstrings!

Swapped F1t2 and F1t1 (sorry flux) to give Pure a speedyish move she can
use out of block to punish bad blockstrings. Lowered its locktime from
0.8->0.4, halved its damage and shrunk its tracer a bit so it isn't the
ultimate punish tool.

Widened Ryo F2 tracer to make it safe on block and get rid of the pesky
f2f3 opening that's only escapable with lsblock and strafejumping
