Evilwm launcher patch

Question

Ok so I was a big fan of evilwm during my "minimalist hunt". I still use it as my floating alternative to Ratpoison (yes, tmpwm can do wonders )
One thing that I've always hated about evilwm was the lack of any type of application launcher, all you could do was to spawn a terminal, and start your application from there.
I wrote this little patch really fasts, it works, but I intend to extend on it (for now you can only launch apps or scripts, but I intend to make it default to dmenu without the need of a separate script)
To patch against evilwm-1.0.1(fresh source, nothing messed with or else the patch could fail):
1. Copy the patch somewhere within reach (I usually put it right in the source's directory)
2. Do `patch -p1 ./evilwm-1.0.1-lich.patch`
3. `make clean && make && sudo make install`
You can now run evilwm with an extra flag, -launcher. The patch defaults to using the application called "launcher" (which should not exist unless you made one called like that). If you have an app in your $PATH that has this name already, no need to pass the flag (ONLY IF that application is actually an application launcher, otherwise make the flag point to your launch script). My `launcher` script ( I keep it in my ~/bin directory, which is in my $PATH )
#!/bin/sh
exec $(dmenu_path | dmenu -nb "grey20" -nf "goldenrod" -sb "goldenrod" -sf "grey20")
chmod +x ~/bin/launcher` and that's it, start evilwm and you should have dmenu run on CTRL+ALT+m (default evilwm MOD is CTRL+ALT)

Enjoy, even though anyone with a minimal C knowledge could have done this

Yes, that's how I used it too, but why not have an 'official' option?
