updated tags to insert in lower-case.
Massive overhaul of theme management in Plugin.
Created filter and action callbacks to handle inserting plugin HTML data nicely into currently active theme, by making use of a Place-Holder or "Portal" wordpress page which uses the same url slug that is set in the plugin.
Added URL Rewrites and query vars for future expansion, and to allow child-pages beyond the Place-holder page's slug to be loaded.
