The API was changed slightly so that has_capability now takes the
whole $context object (we almost always have it anyway)
The $kill thing was removed. If you want to assert a capability
then use:
require_capability('capname', $context);
with optional variables to modify the error message
Misc bugs here and there also removed and code tidied
