* Fix failure to remember that we have constructed an interpolator

window already (#25).  Also avoid using alloca for substantial buffers
* Lose FFT::getFloatTimeBuffer and getDoubleTimeBuffer -- it's too
unclear when it's safe to use them and it's safer to control sizes externally.
In RB with smoothing on, these buffers were incorrectly being used for window-si
zed calculations (larger than FFT-sized).
* Fix some incorrect buffer resize sizes
* Build fixes for OS/X
