Added application class and configured Universal Image Loader
Added book images to MainListActivity

Updated UIL configuration, updated NewBookActivity to get and store
image URIs and updated Boovie adapter to display individual images.
Moved TMDb and Goodreads API initialization to the application class

Also updated the TMDbAPI JAR.
Minor fixes and updates
Updated BoovieAdapter to display movie images

Temporary solution until I fix TMDbAPI.
