Major refactoring; new Entry syntax

CHG: completely rewrote the plugin from ground up
CHG: the syntax matchers are now plugins that can be added or removed as
needed.
CHG: added a (IMHO) better {{entry...}} syntax, simialr to the existing
{{subjectindex...}} syntax.  The old syntax will continue to work.
NEW: bible verse entry how have a verse popup on hover over.
NEW: multi lines now allowed in {{subjectindex...}} markup
NEW: showcount, hidejump, regex options (like pagequery cousin)
NEW: no limitation on number of sections
