We have a [tag:php] tag, and we also have a [tag:php-5.4] tag.

Ultimately, they're both PHP, and I see no reason to have separate PHP tags for each version (the same reasoning was the primary drive, as far as I can tell, for [tag:php5] to be an alias of [tag:php]).

Can we take the [tag:php-5.4] tag and just have that be an alias of [tag:php]?  Otherwise we'll have a thousand PHP tags which we don't need.
