Replaced banner images with optimised versions
Fix: resolved cross browser display issues (removed autofocus from input elements to stop some browsers trying to force that element into view). Improvement: transitions between inactive and active states for hidden elements/panes. Fix: when directed to the receivers section of the Industry Focus page (by clicking the 'Learn More' link on the second image of the home page carousel) the Industry focus navigation wouldnt work on the first click, this is now resolved.
