Prevent event swith enddate before startdate
add 9.3 to the feature matrix so that thom can start updating it
remove the code to add default user_options for the upcoming MW 1.19 upgrade

random functionality like preference handling
change example rewrite rules to something that also catches the "nocache"
versions of the mw pages
fix a minor typo
Add Homebrew to the Mac OS X download page.
