Fixed Issue #2348 (WIP) - Initial iteration of added logic for send user to template app gallery

As per the comment thread for this issue between @SteveALee and I, this is my current MVP for this. I intend on turning this function into a more elegant and dynamic "preview window" like menu feature in the near future. Any feedback or guidance on implementing this would be greatly appreciated.
I don't think we have one, but if we're hardcoding a URL into the codebase, it'd better be a good URL ;)

Is there a "generic" gallery search URL that effects the same sort of list we can use instead?
