Feature homepage templates

Hello,

Two possibles for the basic homepage, one with an opening text block and one without.

These are up for preview on:

http://odi-stg.whiteag5.tryingitout.co.uk/home.html
http://odi-stg.whiteag5.tryingitout.co.uk/home_text.html

PLEASE NOTE: this PR does not use any of the styles that were done over the weekend, as they badly broke all the module blocks. This PR has just added to the styles inside the /templates folder, not the ones in the /app folder.

However, this should not cause a problem as the new styles are located in one block only in /templates/sass/main.scss, beginning around line 276 with:

/*------------------------------------*\
    HOMEPAGE
\*------------------------------------*/

Do a search for .home-opener and you should see them.

After this we can look at getting everyone's styles consolidated and then hopefully I can fix the broken module blocks and the People page's styles.

Thanks,

Gareth
