Update p5-Squatting to 0.81.

Changes from previous:
0.81 2011-04-27
  - Slight improvements to Squatting::With::MockRequest were made
    to facilitate doing static exports of Rhetoric sites.

0.80 2011-04-27
  - [ MAJOR API CHANGE! ]
    - You don't say:  use base 'Squatting' anymore.
    - When creating a Squatting app,
      you just say:   use Squatting;
    - You don't say:  use Squatting ':controllers' or
                      use Squatting ':views' anymore
    - use Squatting takes care of what those statements used to do.
  - Squatting::H->merge renamed to Squatting::H->extend to
    be consistent w/ the way these words are used in contemporary
    Javascript libraries.
  - Added Squatting::With::PerHostConfig
  - hacked bin/squatting so that the console experience is a bit nicer.
    App->get and App->post will work a tiny bit more reliably.
