removed .pch from .gitignore

General code clean up, esp. Mixer3D::overlapConvolution. Chasing down playback bug when azimuth=0.
More code clean-up. Still chasing down playback bug...
Audio object failed to play when azimuth and elevation == 0. Due to uninitialized prevAzimuths and prevElevations. Working now.
more misc code cleanup, does not seem to support > 1 audio object
kept arg error-checking and certain variable names, removed filterFlag and signFlag as these are unnecessary, re-ordered iter vars (i.e. j, i to i, j), combined certain for loops when possible
changed clFil, lFil to complexLeftFilter, leftFilter, nTaps to filterLength, actually removed signalFlag and filterFlag
fixed #include <string> bug, working on returning player reference, not player * in World::getPlayer()
