Fixed a Multitap linking bug. Added freq() to Multitap.

When declaring Multitap as a pointer (i.e. Multitap<> *delay), an error was thrown during compilation. adding "this->" before mIpol() fixes it. I've also added in a freq() method for individual taps in Multitap.
Fixed Multitap.freq() argument to be consistent with Delay.

Domain: use pointer instead for head of observer linked list
Accum: cache freq to int to save multiply in freq()
DomainObserver: remove local mSPU and mUPS to save memory and reduce complexity; intermediates can be declared in derived class when needed
change default sample type from real to float
bump version to 0.9.7
