Deprecated baseCategoryValue and changed its implementation to defer to
shortCategoryValue

The previous implementation of baseCategoryValue made the assumption
that 'O' was always the element added to the domain, which is not
generally true. Rather than remove the method completely and break
things downstream, I've deprecated it and changed the implementation to
match shortCategoryValue.
remove condition that 'word' regex not contain a date so that we can match long 'word's, e.g. urls or elements of raw html, without crashing
