Replace PHP Short Open Tags - Fixes #11

Lots of testing needed on this one just due to the number of changes, possibly every single PHP file, I am working through it. The actual changes were all performed with the following command across the web folder.
find . -iname '*.php' -type f -print0 |xargs -0 sed -i -e 's/<? /<?php /g' -e 's/<?\/\//<?php \/\//g' -e 's/<?\/\*/<?php \/\*/g' -e 's/<?\=/<?php echo/g'
So far I have scanned across the changes and looks like they were almost exclusively <?= tags that have converted to <?php echo successfully. Looking to see what I can do to automate the testing, something like comparing the resultant html pages, as they should be identical.
