Angle brackets should be removed from display

[haukex]

The word list includes entries like referrer <referer>, where the part in angle brackets is a common misspelling, so that it can still be found via full-text search. But the parts in angle brackets should be hidden from the search results.

Reopening because the current code doesn't correctly handle the case of <name--dropping <name drop>>.

Edit: This is the only case of nested angle brackets in the dictionary, so it could instead be fixed in the dictionary instead of the app.

Fixed in dictionary, thanks @frituc !
