[Open-Legislation] Updated the working group page

[Rufus Pollock]

Hi All,

I've just tidied up the Working Group's current home page:

<http://wiki.okfn.org/Working_Groups/Legislation>

In particular I've added a revised Purpose sectoin based on an irc
chat with Friedrich a few weeks. It now reads:

1. Define the area of Open Legislation - what it means and what it involves
2. Act as a central point of reference and support for people who are
interested in open legislation
3. Identify practices of early adopters, collecting data and developing guides.
4. Act as a hub for the development of low cost, community driven
projects related to open legislation

What do people think?
