basic template structure for new MP page

Moving to having the header, footer and page content 'templated' which
will then be included by the file that displays them. All the data will
be set up outside the templates which should only do presentation.

This only includes the templates and not the logic page

also initial rough sass for the layout
update width and default column gutters in line with style guide
fix colours in line with style guide

change settings colours, fix other hard coded colours in style sheet
set specific styles for footer columns

rather than relying on the in build foundation ones use classes and ids
reduce overview and panel header levels

better represents importance on the page
set some default font sizes
clear out some old css
make whole brand element in header green
simplify layout of main page countent

remove header from main content, add in the sub nav things and reduce
the number of divs we use to layout the panels
Also correct row class names
add content header section back in with hardcoded placeholders

Uses a wrapper so we can set the background image approriately for the
assembly/member and then can layer the shading over the top for
legiblity.
include and use Source typeface
set size and weight of header tags
bump up header classes for main content

increase h2 -> h1 etc
remove list style from panel navigation
set base font size to 18px
site name should be centered in box
rough initial style for MP speech search box
right align party and constituency cell
use em-calc rather than emCalc which is obsolete
correct font weight for tab navigation
