Flipped TerminusCollection; defaults to fetchless; added APICollection

[TeslaDethray]

This changes how TerminusCollection works in these ways:

• TerminusCollection no longer contains API-accessing functions. Those have been moved into APICollection.
• TerminusCollection now has getData and setData functions.
• Models are populated with the stored data.
• Added reset() function. Collection filtering can now be reversed with reset() (which sets the models to null again which will require another fetch upon model retrieval using the saved data).
• APICollection retrieves data and stores with setData.
• Removed redundant getCollectionData() and getMembers()
• Removed options param from fetch
• Removed listing function from TerminusCollection

Other changes:

• Removed some redundant functions
• Removed Loadbalancer(s) model & collection - nothing in Terminus uses them anymore.

This is triggering my php alarms, but I guess it's no longer a problem since we don't support older versions of php. Old instincts die hard.

At first I was using $this->data, but then I fought it: "Do you want to change every instance of it if you start doing something else with the data?" While I couldn't decide what might change, I figured I ought to encapsulate against the future anyway.
