Change fsqrt() to sqrtf(), etc.

Replacing all occurrences of

fsqrt -> sqrtf
fsin -> si
fcos -> cosf

with the attached patch allows the game to build and run, but the game's math still seems off.  Cells take minutes to accumulate any amount of damage, so the population has barely changed at the end of a 4-minute match.  It's not supposed to be this slow.
