Release bug fix version

[Kevin Lai]

Hi all,

I released a new Tycoon version (0.5.0p81) that fixes bugs in the bank
account setup code and updated the documentation to reflect the fixes.
If you have been having problems with "tycoon user setup", then you
should "yum update" to the new code and see the updated tutorial at
