Support "bracketed paste" mode. This adds a -p flag to paste-buffer - if

this is used and the application has requested bracketed pastes, then
tmux surrounds the pasted text by \033[200~ and \033[201~. Applications
like vim can (apparently) use this to avoid, for example, indenting the
text. From Ailin Nemui.
