added some og data for better sharing
whoops, it wasn't URL encoding the second postcode, siily me! Fixed now
now gives you a cleaner URL if it is a share link to the homepage
put postcodewars.co.uk back into original share url because of a bug it caused with facebook open graph
fixed silly double = sign error causing the equalitive not to work
added a description meta tag, for yet again better sharing functionality
changed them all to, do cache because it was killing our load times so much that FB was messing up the sharing functionality
Added code to format the postcodes into caps and with a space, it into AA1 1AA or A11 1AA etc
added more in depth checking to check if the postcodes are valid, note, it doesn't check whether they exist or not, also doesn't try to format them if they are invalid.
fixed a bug (discovered immediately whoops) where you need to put the beginning and end carats (^,$) in to make sure there is nothing else included with it
fixed a typo in regular expression
