Renamed LongDescription to Description, to better serve its new dual role as "holder for a place where inline tags can occur";

Removed Tag::setDocblock() in favor of an additional constructor argument that defaults to NULL;
Tag::createInstance() and Description's constructor now have a second argument, allowing the specification of an owning DocBlock;
Description::getParsedContents() assigns the Description's owning DocBlock object when creating tags.
