Please fix image pasting from Firefox

@sam
Can you please fix Discourse so that clipboard images can be pasted directly into the message window from Firefox?

Thx, --Mitch

Sorry about that, it is now fixed

(Still takes some time to upload stuff and it also gets"stuck" sometimes…)

Sorry about the stuckiness, I just deployed a fix, let me know if its working better now.
