safe-paste plugin

Pasting into a terminal can be dangerous (see http://thejh.net/misc/website-terminal-copy-paste). I certainly do it accidentally all the time.

Luckily many terminal emulators can indicate to their containing programs when pasting is happening. This plugin (shamelessly copied from http://www.zsh.org/mla/users/2011/msg00367.html) allows you to paste into zsh runnings inside xterm/urxvt/iTerm2 safely by preventing any code from actually running while pasting.
