* Add sudoedit support

* change describtion of sudo plugin

Press esc-esc once to add sudo (normal behaviour), press it twice
to remove it from the beginning of the line.

I.e. when prefixing the current command-line with 'sudo ' maintain the
current cursor position instead of jumping to the end of the line.

Plugin won't load automatically if added to variable $plugins, if name schema different than $name/$name.plugin.zsh is used (see is_plugin() in oh-my-zsh.sh).
