Fix bug where returning to match_organism challenge throws exception

In general we need to be careful of get().get() pattern, and replace
with getPath() where possible.

Fix SC.Busy error when saving journal post draft

Update of user model should only happen when user is ready

Rm loading of obsolete "articles"
Don't load chal drakes on argumentation, invis, and select-parent chals

These challenges don't need preexisting challenge drakes to be downloaded
from the DB. Unsure why they are that way -- assuming I probably copied
old settings from other challenge types.

This will speed up loading of these challenges.

Reset chromosome-pulldown views on activity navigation

dragonGenomeController was not getting reset alongside all
the other controllers, so chromosome views could be already
populated when navigating to them.

This was usually obscured by the fact that new challenge dragons
would be created instantly, but when that would happen slowly
(especially when LOAD_CHALLENGE_DRAGONS=true), we would see
expired dragons in the pulldown views.

Return empty array when querying DB for nonexistent user

Currently when a new user logs in for the first time, we query
the DB with /users.json?username=nonexistent_username. This then
returns all users, which in the production db is a very large list
(~9MB...). This can take over a minute to be received by the client.

This change quickly returns the empty array instead.

The Geniverse app seems to handle this change just fine.

Monkey-patch SC.View to support toolTip property on all views

This already exists in SC 0.5+, but not with the version we have.
Not worth adding this to the fork of SC we are using, easier just
to add this small change here.
Add ability to show QTip tooltips on elements.

In the inActivity state, we can call the showInfoDialog
to append a speechbubble-like tooltip on an element.

The tooltip appears immediately, and disappears when the
element is moused out of or the bubble is clicked. From then
on the tooltip acts as an on-hover tooltip.

Add the jQuery QTip library:
