 I've seen (and wrote) a lot of plugins which manually build out each HTML
 attribute as a loop, escaping each value and then removing any attribute
 that has no value. Wouldn't it be nice if there was a function that does
 all that for you?

 This patch introduces a new function {{{html_attributes}}} which accepts
 an array and builds out a string of attributes whilst sanitising the
 values and removing any empty attributes.

 I've also updated any uses in core removing the logic and using the
 function instead. There's probably a few instances still left to update,
 but this is a good start.
