I went through all of the source code replacing anything that is now
possible using appcompat-v7. appcompat-v7 is the official way to handle
backwards compatibility, and it is supported by Google and others. Using it
as much as possible should make the code more maintainable and readable by
others since they'll be used to seeing the appcompat-v7 patterns from other
projects.
