Cache frendly

Hi dr.stjepic,
I have not implemented any custom Cache plugin support, so this Plugin is a “regular Plugin” in terms of Cache compatibility.
However, most Cache plugins will probably take a snapshot of every page and then deliver the static content for a certain amount of time without running the plugin code again. In this case, real-time information like “we’re currently open” will most probably not be as accurate as with cache plugin usage.
