several changes that allow for changing pages without hash changes:

- allowed prevention of hash listening during a particular hash change
- allowed $.activePage to remain set on previous page when an untracked page is open (return pageshow event false to use this feature)
- moved setting and resetting to base urls and made sure they update at the right moment for both new pages and those previously visited.
- changePage now accepts an array as first argument, allowing you to specify both [from,to] pages, whereas non-array types would refer to the "to" page, assuming "from" should be the currently viewed page
- error requests never generate a hash change now
- edited the ajax error to appear in the right location when scrolled

Essentially, plugins can now create page changes that are not tracked in history, which is a dialog critical bug.
