GetGamesList, Search Bar Position, htaccess fix

Fixed: GetGamesList API Parameter Lookups - @teterum 's fix didn't take
into account that if the name parameter was not supplied the script
would exit, also removed single quotes around $platformId in SQL query
as the platform id is an integer not a string.
Fixed: Search bar position in large page header - @chaeril 's fix proved
broken on both the latest stable version of chrome and firefox - search
icon and text input field were shifted about 18 pixels downwards from
the search container.
Removed: Line at bottom of htaccess which was trying to auto prepend the
globalsfix.php to all php files including the API which did not require
it, this caused API breakage in some server environments such as WAMP.
Fixes from @chaeril 's pull request

Fixed: @chaeril had removed the facebox modal plugin includes from the
head of the 'templates/front.php' file causing the 'share via email'
functionality to break.
Fixed: Moved the Facebook Javascript API library include to bottom of
the "templates/footer.php" file as it would be best loaded after the
rest of the page content so as not to impact performance, and also
because it contained html that should not be inserted in the <head>
section of a document, thus preventing the Facebook share button from
showing.
