Version bump to 1.0.0-alpha-1.
Droppin' the bomb on some code.  Introducing the new Get_The_Image class.  This will make it easier to reuse code.  It also encapsulates some of the mess we've had in the past.  This deprecates many of the private, internal functions.  Some of the arguments have changed (backwards compatible).

@todo - Testing.  Testing.  Testing.  Inline doc updates.
