Add default charset utf-8 to htaccess
Add $input->urlSegmentStr which returns a slash separated string of all active URL segments. This makes it easier to check that there aren't additional/extra unnecessary URL segments present, when a 404 should be thrown
Add new Pages::saved hook, for syntactic consistency with the other Pages hooks. Same as Pages::save, except that it's called before other hooks like added/moved/etc. Whereas Pages::save is called after. The distinction usually doesn't matter, but mentioning it just in case it does to anyone.
Additional improvements to the new bcrypt password hashing options
Add an option so that Comments or other modules can temporarily disable caching of a page.
Updated ProcessModule so that it performs a redirect after a module edit. This gives us more predictable/consistent behavior in many situations.
