Commit changes to compiled JS files

It appears that the coffee compilier has changed the format of the JS
code that is produced from the build process. To avoid having PRs that
reference JS files that haven't substantially changed, commit the
changes here as once commit.
Update README

Poltergeist no longer defaults to port 44678, it simply runs on an open
available port.

Render full window size if document has no height

When rendering a screenshot with `:full => true` on a document which has
a height of zero, the call fails silently with no screenshot being
created.  This situation can occur with pages that use absolute or fixed
positioning for all content, for example.

Changed to use the `documentElement`'s `clientHeight` & `clientWidth` as
a fallback, which will result in screenshots the size of the viewport in
that case.
