MediaWiki core change I04b1a384 added support for i18n of API module
help. This takes advantage of that while still maintaining backwards
compatibility with earlier versions of MediaWiki.
Once support for MediaWiki before 1.25 is dropped, the methods marked
deprecated in this patch may be removed.

The API provides more details about HTTP errors, so show these to
the user instead of a generic "An unknown error occurred."

Allows for more broad filters to check for a given right, rather
than having to check against multiple groups, which becomes useful
with global groups.
