Version 1.3

* next_page and prev_page now rely on internal measurements measured at
initialization in order to find out how many pages there are.
* stop_timer now works
* Added some useful comments to the settings.
* Added "force_pages" option - it forces a certain number of pages.
Useful for partial scrolling without a "tail end".
* Added "bind_hover" option (on by default) - if a timer is present,
this option makes sure that the timer is stopped when the user hovers
the carousel and starts when the user hovers out.
* Some minor stylistic changes
* Link binding now has preventDefault() which gets rid of annoying page
jumping.
