WIP: Resolve "Group search autocomplete fails on committees (containing + sign)"
autocomplete JS encodes + sign to %B20 - which led to empty results in the group directory Unfortunately the URI Encoding is needed for page sharing - so we have to keep it. Committes are found in the group directory after replacing the %B20 by + in the SQL query for group search But the search string shown in the query field still is broken (rainbow%2Btest)
Closes #140 (closed)
