The project list screen was taking a long time to render over a large
amount of projects (1,000+) and with even larger number of projects
(3,000+), it could make the browser unresponsive.
Project list screen now uses pagination to resolve this issue. The
number of projects displayed is determined by the 'Maximum Page Size'
user preference.
