Small update to the Escape contest rules

We've made a small update to the Escape contest page regarding the use of logos. The changes are as follows:

• In addition to your name/team name, the title of your entry and the Escape logo we are now asking that you include the URL to the contest page. This information does not need to be prevalent, it just needs to be included in the submission images somewhere. (In the past, people have added a tiny letterbox to their submissions and tossed this kind of information in that space.)
• You now have the choice to use the logo we created for the Escape, or you can create your own. Please see the contest page for complete information regarding this addition.
