tulip.world() UI short term changes

[bwhitman]

Before more people use it:

• [ ] require a handle and prepend messages with the handle
• [ ] UI should only show the last ~35 rows of text
• [ ] text entry widget for ui
• [x] upload files / packages of files for sharing
• [ ] a poll / refresh button to the right of the text entry widget

Automatic refresh would be fine, but on Tulip CC the ssl network access disrupts the screen refresh at this time. I think we can fix that, or we can just call tulip.display_restart() after each network access. Or, make it more like a web1 BBS and force a manual refresh.
