Auto hide cancelled projects

[sh-rn]

Scenario:

Hiding cancelled projects automatically will remove clutter from the projects table list.

To do:

• auto hide a cancelled project after 7 days (a setting that should be able to be changed in config in a later version)
• add checkbox option to hide cancelled projects - default to selected - the user can then uncheck this and also show their cancelled projects.
