Increment version for release to bower and NOM

Also fixed up github repo name.
Remove unused spec and 'ddescribe' -> 'describe'
Provide an isGiven function to identify objects Given objects
Downgrade jasmine-node to a non-broken version
Remove extraneous slash from directory name
Bump version to 1.0.0-beta3
Removed the immediate form

The immediate form was the ability to define a value non-lazily, like this:

```coffeescript
    given foo: 'bar'
```

instead of:

```coffeescript
    given foo: -> 'bar'
```

Accidentally omitting the function would cause *immediate* evaluation of the
variable which has proven to be a trap for the unwary at my day job, and being
able to support both forms offers zero advantage.

Given will now emit a meaningful error when forgetting to wrap the RHS in
a function.
Release 1.0.0!
First (ugly) cut of the home page
Updated the web site

It now sucks less hard
