[PATCH] Add wtype as a typer

[jimum3bxg6c4 at gmail.com]

From: cedric <gaspotrash at gmail.com>

There are cases where wtype is prefered over ydotool.
There might be also cases where ydotool can be prefered in an X11
environment.

This patch allows the user to choose which typer to use, among:
- xdotool
- ydotool
- wtype

It is also fully backward compatible.

passmenu --type          # will work exactly as previously
passmenu --type wtype    # will choose wtype as typer
passmenu --type ydotool  # will choose ydotool even in a X11 environment

 Note that the latter requires access to the [uinput][] device, so you'll probably
 need to add an extra udev rule or similar to give certain non-root users permission.
 
+Optionally you can force a typer (xdotool, ydotool or wtype) by adding it as a
+parameter to `--type`. e.g.: `passmenu --type wtype`.

 # Usage
 
-    passmenu [--type] [dmenu arguments...]
