Title: Made changes so that MemeGenerator can be used outside the command line.

* Added MemeGenerator.memes which returns a list
of locally available meme images (using their short name).

* Added MemeGenerator.meme_paths which returns a hash of available
memes (keys are short names, values are paths on disk to image file).

* MemeGenerator.generate now accepts nil values for top and bottom
captions.
