Disable polling for channel WHO data (for now).

Node is choking up to handle WHO responses for channels like Freenode
with a huge number of nicks. We'll try to figure out a better and
sane way to do this.
Scroll to bottom of chatlogs when chatlogs are first shown.
On entering chat messages, don't scroll to top.
Make display/highlight of chat components depend on highlightChannel()

rather than on selecting a server room.
Scroll to bottom of chatlogs when user sends message.
Don't add duplicate listeners to scrolltop event on chat logs.
Always show scrollbar on chat logs table.
Sort server/pm logs on the basis of creation date.
Replace <table> with <div> for server chat logs.
Fix showing user info when PM is selected.
Optimize scrollbar in chatlogs table.
Smooth pagination of channel nicks.

Keep a window of max 40 channel nicks visible and paginate by loading
10 nicks up/down.
Bugfix in setting chatlogs scroll when new chat logs arrive.
Maintain scrollTop() value of chat logs table if user hasn't scrolled to bottom.
Refactored Fiber implementation to be more granular.
Fix scrolling to bottom of chatlogs table.
Updated meteor deps files.
Added SUPER_USER fields in server settings dist file.

When waartaa server is started, if a SUPER_USER account does not exist,
it will automatically create a SUPER_USER account and add new server connections.
Added setup script for waartaa and updated README.
Update README
