Add option 'S' to projects REST API to support query offset

List projects endpoint has an option to limit the number of results
returned but it was missing an option to start at a nonzero offset in
order to support results paging.

Add and document 'S' option which allow to query project list starting
at a nonzero offset. Also add missing documentation for the 'n' option
which limits the number of results.

Those 2 options will be then used to render project list with pagination
in web UI.

Implement pagination in project list screen

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.
