Update README.md

I added backbone.subroute to the jam repository
Use slice instead of substr to help IE8.
Fixed #13 and bumped version to 0.3.1. This was an IE8-only issue where manually including a trailing slash in a subroute prefix caused a double slash to appear in the fully-qualified route. Thanks to @mikesnare for logging the issue and providing the fix!
Override the route function instead of doing route manipulations in the constructor.

This allows the developer to use the route function on a subrouter and
still have it transparently register the route as a prefixed subroute.

Fix jasmine specs

All the specs work now.  There were 2 issues.

1. Because we were overriding the route function instead of updating
the routes hash, the routes hash wasn't being updated.  I've added code
to the route function to put the new route in the routes hash.  Some of
the failures were due to the test expecting the prefixed version of the
routes to be in the routes hash.
2. There was a genuine bug wherein if you added the "" default route,
the route that ended up getting added was "prefix/" instead of the
correct "prefix".  Fixed.
