implemented android beam for sharing anime/manga
don't display "touch to beam" for activities that doesn't have beam functionality
check if anime/manga object exists and display toast if data couldn't be loaded
Don't crash if anime-/mangadetails could not be loaded from API. Catching this here makes use of getAnimeRecord and getMangaRecord easier as a null check is sufficient
Merge pull request #90 from d-sko/beam2
