Branch nsound-0.4.0 FIR Filters

I've just checked in some basic FIR Filters: low pass, high pas, band pass and band reject.

You can even dynamically filter audio on a sample by sample basis!

For an example take a look at:

nsound-0.4.0/src/test/test_filters.cc.

You can check out branch nsound-0.4.0 by doing:

$ svn checkout https://nsound.svn.sourceforge.net/svnroot/nsound/branch/nsound-0.4.0

Try it out and submit bug reports!!
