There are lots of calls to $user->isAllowed which could be simplified
using available accessors like canEdit(). So simplify those calls and
avoid duplication.
Note that using canEdit also fixes a bug which affected blocked users:
we used to show e.g. the import link, and not to display as disabled
several text fields, while blocked users cannot actually edit filters.

Now the required need will be abusefilter-modify OR
abusefilter-view-private for /tools, /test and /examine.

This should fix every error with excluded rules, leaving only the one
for $wgTitle. A double check would be nice in order to avoid regressions
due to stupid mistakes.
