Updated Icons
Version bump, and fixes #153
More fixins for the progress dialog
Nibbler.min.js has disappeared
Tests and poking around on the device both seem to work with the full 1.0
Zepto release.  While this is unlikely to rectify the flaky bower download
problems, we're at least on a semantic version that gives us more latitude
to try various things to work around it.
Merge pull request #155 from SpiderOak/update-zepto

Tests and poking around on the device both seem to work with the full 1.0
Merge branch 'master' into issue-151-alternate-server
Refactor the AccountModel slightly so it uses the current
spiderOakApp.config.server value as the basis for the various server
settings.
Rectify the logout process, so that the responsibilities are in the right
places and the UI response to logout can be triggered by anyone:

* Trigger logoutSuccess in the AccountModel.logout() method, after actual
  logout has occurred.  ("logOutSuccess" was being mistakenly triggered.)
* Enable calling the logout method without a successCallback.
* onLoginSuccess in app.js does the UI cleanup, triggered by the
  logoutSuccess event.  It does *not* call AccountModel.logout(), since it
  would be infinitely regress by that method's (now correct) triggering of
  the event.
* MenuSheetView now re-renders itself when logoutSuccess is triggered.
* MenuSheetView now properly calls AccountModel.logout(), rather than
  triggering logoutSuccess.  (I believe it was only appearing to logout,
  before!)

This provides the ground for changing the server setting to do a logout
and have the UI clear, properly.
Implement a view by which the primary server configuration is changed.

If the change happens during an authenticated session, the session is
logged out and the UI is reset.

If the change happens outside of any authentication, the user is returned
to the top-level settings view.

The top-level settings view is updated by virtue of triggering a new
settingChanged event - please use that for other settings changes.

(The css changes are expedient - some thought about organized settings
styles is needed.)
