While there is no need for TOGGLEINPUT on the default programstails
screen there is nothing stopping theme developers adding links to
other web pages that may need it.
I like the idea of adding something to indicate the current toggle
state and will probably add a statestype to indicate the current state
at least to MythBrowser. A dev has been threatening to remove the
current program details page because he doesn't like the fact it uses
html and will replace it with something else so not sure I want to
spend any time updating that one. I doubt most users even know the
program details screen is a dynamically generated html page or care if
it uses html or not so long as it shows the info they want :)
