Add Valuation::getSatValue() so that theories can access the current
(propositional) assignment for theory atoms.
Fixed Debug/Trace as discussed in bug ticket #252 and on the mailing list.
This implementation leads to some compiler warnings in production builds,
but these will be corrected in coming days. There appears to be a small
speedup in the parser as a result of this fix:

Cleaned up a few CD Boolean attribute things.
Various small fixes to coding guidelines / test coverage.
This commit:
* Resolves bug 252 (tracing not disabled in production builds)
* Resolves bug 254 (implement CDAttrHash<>::BitIterator::find())
