Labour Party List updated

I've made a few minor changes to my candidate database.

• David Parker - Following his resignation from Parliament I've removed him from the Labour Party list.
• Steph Lewis - As she has announced she won't stand at the next election, I've removed her from Labour's list, and as the candidate for Whanganui.

I've also made a host of backend changes which make it far easier to update the candidates and party lists - so it should be simpler and faster to keep my database as up to date as possible ahead of the next election. As always, if you think I've missed any data (eg others announcing they are standing or not standing) - please let me know!
