VWR-26942: Nederland CA was causing issues when it was mid-CA.pem, moved to end for testing.  We are still investigating the real issue, but this may be a sufficient patch

removed all references to basic mode

Remove the viewer side automatic logout after extended away time.
Note, however, that the server still logs you out after 30 minutes
away: see SVC 7251.
Allow more time (10 seconds vs 2 seconds) after initiating Away status
during which mouse movements do not remove the Away status.

The selection distance limit was set at 64m. Now that we have 64 meter prims
this means that you can see objects that you couldn't reliably select, or
couldn't always scale up to full scale. Doubled the limit to 128,
and selecting and scaling operations appear to work fine, even for 64m objects.
