Turns out the pagination system is somewhat chicken and egg with respect to
determining the number of pages. The query needs to be sent to the database
to fetch the page content so that the database can also count the total
number of records available.

This commit attempts to remove all coding standard warnings emitted by PHP
7.0.

Add ticket count to page bottom. Team-assigned tickets show up in "My
Tickets"

No. Seriously. Like from 11k seconds down to 0.3 for a full-text search on
several thousand tickets.

Use http::build_query instead of inline urlencode

Also re-implement the "exclude answered tickets" and "exclude assigned
tickets" from open queue options.
