Storage policy stats was not well parsed in account stat. This
patch parses the stats and print out the stats in a format like below:
$swift -A http://swift_cluster/auth/v1.0 -U test:tester -K testing stat
Account: AUTH_test
Containers: 5
Objects: 1
Bytes: 2097152
Objects in policy "golden": 1
Bytess in policy "golden": 2097152
Objects in policy "silver": 0
Bytes in policy "silver": 0
X-Timestamp: 1404697760.88809
X-Trans-Id: txec519e24b44a413abb705-0053da2dcb
Content-Type: text/plain; charset=utf-8

When you stat a container or object with the verbose flag the full path of the
reousrce will be displayed with the token similarlly to how an account stat
displays the auth url and token.
* move some logic out of bin/swift.st_stat to test it
* new module swiftclient.commnad_helpers for code you want to test
* moved prt_bytes into swiftclient.utils to test it
* fixed IndexError with prt_bytes on sizes >= 1024Y
