Added a new model to represent Coordinating Nodes in DataONE. When the
app starts all the node information will be retrieved if there is a
nodeServiceURL specified in the theme AppModel. The DataCatalog view
will listen for the member node list in this Coordinating Node model and
construct a filter checkbox list of member nodes. The filter list now
will display the loading template in this spot until the list is drawn.
Some changes to that template's HTML and styling were made for all
themes.
