I'm really not a reverb expert, and I'm open for suggestions. I would 
set the following demands of such a change though:

1) It should not be more CPU intensive than the current one
2) It should be LGPL or something compatible with LGPL
3) It should not add a long dependency chain
4) It should be able to work with both single and double precision 
floating points (can be set at compile time, as the rest of FS)

Perhaps such a change of reverb component could be introduced gradually 
by a conditional build.

As a side note, today I committed a patch from ticket #89 which, 
according to the reporter, fixes or improves the reverb sound on sample 
rates different from 44.1 kHz.
