improve copy and paste experience






When I copy from a card's view mode and paste it somewhere it has a bunch of spans which can mess things up.

When I paste from a URL copied from another card's arrow link to the TinyMCE editor the link does not paste at all. I would expect it to paste, but to convert the link to the shortest form possible, taking out the server name if I pasted from and to the same server, leaving me with a /relativelink

Bullet point list (and probly numbered lists?) formatting is lost (after saving) when pasting in from EtherPad.


Lots of issues with Word, and copy-and-pasting from browser pages.
