Submitting to work on another machine
Starting HTTPPost

Need to wrap this stuff in a worker thread to avoid main thread net io
exception
Post should be there, but with problems

Not sure why, but it's getting a "Method Not Allowed" exception when
building the JSON object from the received data
Fixed post request

Posting works!!! YAY!  But just once...then it crashes... :(
App runs reliably now

Fixed issue with async tasks. They can only be executed once.  Also
disabled the "New Card" button while pulling new card data.
HTTPGetCardClient now properly handles 301 & 302s.

When encountering a 301 or 302 status code, the connection is properly
refreshed with the new resource so things run smoothly.
