Moved embedded AsyncTasks in Login.java to their own files.

Tried to be a little more tidy by moving the AsyncTasks to their own files.
However I encountered a problem where I need to retrieve the data from the
Asyncs and I need to use get() function, but that freezes the main UI. I
need to figure out how to retrieve data without using get. onPostExecute
seems to be the answer. I might pass the data back through the activity's
intent. Yeah that could work.
