~ make front page reponsive

[Spike for interum front page redesign] 

This template apparently improves search ability.
It also makes the front page mobile friendly and more lively to look at.

- The carousel still isn't working, I think it might need a little js to nudge it. 
A still image in it's place maybe a better option anyway.
- I have purposely keep the css together to make changes and tweeks easy until we know what we want.
- box-sizing will probably need the following mixin;
`
.box-sizing (@type: border-box) {
	-webkit-box-sizing: @type;
	-moz-box-sizing:    @type;
	box-sizing:         @type;
}
`
It may also need pollyfill for ie7 see here
