[PATCH] don't show x-foo tags in search view

[James Vasile]

My filters create tags like x-bogotrained-spam that are for internal
bookkeeping.  I don't mind seeing them in the 'show' view, but I didn't
want them cluttering my 'search' view.  This patch omits x-foo and X-foo
tags from the 'search' view.
