[pass] Patch: ability to type out password automatically using xdotool

[Raphaël]

Hi,

I did something similar using xdotool in my custom version of passmenu:

Workflow is:
- In your browser copy the domain name part (ctrl-l ctrl-c)
- run passmenu --type (keybinding of your choice, eg: ctrl-shift-p)
- 1) if a pass file named after the domain is found,
     it's offered for selection
     and "login<TAB>password" is expected inside
- or 2) if another file is selected, then a line matching "domain<TAB>login<TAB>password"
  is expected (grep for "domain")
- credentials information is stored (in a variable)
- a Xmessage popup asks to focus the login field in the navigator window
- one second after pressing enter, xdotool is used to run "ctrl-V TAB ctrl-V"
- clipboard isn't apart from domain name

I use it daily and it works well but the only annoying issue is
related to a xdotools bug.
I can't get it to automatically store the current URL into the clipboard,
ie: "ctrl-L ctrl-C", thus the extra need to manually copying this into the
clipboard.

It may not please all who think domain and login should be kept "clear"
and only use pass/passmenu to paste password (and doing the domain/login
typing manually or by other means)

But in my case having the possibility to store multiple domain/login
couple per files and having generally only one login per domain makes
this version useful.
