Sanitise form input

Removing errors when a user enters information can help avoid un-needed support queries later.

• Consider normalising podcast names or artists to remove trailing spaces or double-spaces. "My Amazing Podcast" is not the same as "My  Amazing Podcast" nor is it the same as "My Amazing Podcast ". This can cause problems with in-app searches and services that attempt to match podcast names across different services.

In PHP, the following code will trim and remove double-spaces:

$str = preg_replace('/ {2,}/', ' ', trim($input));
