// Interstitial Pluggin

// v .806 msgkill when exiting to adobe website.

// v .805 jg_dialogue'd new windows opening more jg_dialogs, fixed nameing convention. No need to update a tag's id name.

// v .804 fully jquery'd

// v .803 added support for newer versions of safari and chrome. instead of switching the contents of window -> now opens popup.

// v .802 added internal value for internal linking without having url launch in window
// use parameter {internal: true} when calling pluggin.

// v .801 Placed iframe for ie6 form elements.

// v .8

// Notes on using this plugin

// DOES NOT PLAY WELL WITH FULL SCREEN FLASH!
// Do not use anim time when dealing with flash objects
