Update node action display on web

Update node action display on web to take NODE_BXFR and NODE_XTRN into account.

This was done with a call to presence_lib's node_status() method, which was updated with new options to allow certain information to be excluded (because the Who's Online panel on the web already shows this information). The additional options were implemented in a backwards compatible way to ensure existing calls to this method don't see a change in behaviour.

The extended_status() method was also updated to trim the trailing null bytes (they don't get displayed on the website, but do get included in the system.ssjs node-list response)
