Wrote a bunch of logic to fake session activity to figure out the client side slowdown issues with lots of active users. Toggled by setting 'fake-session-activity' on ServerEvents and then opening sessions.
lots of tweaks to improve rendering performance. Cacheing user views now, and accumulating them in a document fragment instead of adding them directly. Sorting is also disabled.
Minor changes to where code is for session debugging.
Resolved conflicts. moved open-session/close-session triggers to the base model, per the new thin ServerEvent models.
Moved around the debugging code a little. Fixed its behavior to reflect changes on master to logging in server-models.
Removed the sorting events entirely, rather than just not sorting.
Minor cleanup in views to remove debugging code.
Switch from sass to stylus

Addresses issue #100.

Switch from compass + sass to stylus + nib.  Stylus syntax is almost
identical to SCSS.  The only differences pertinent to what we had is
that it's strict with white-space, and uses " = " for variable
assignment instead of ": ".

This PR uses the connect middleware strategy for compilation that
intercepts all ".css" requests and looks for an associated ".styl" file
to compile as needed.  If we ever got real for-serious traffic such that
static were a bottleneck, we'd want to use a different strategy.
Fixed typo in load simulation.
