make it easier to install nwm

[dominictarr]

I've added a bash script to make nwm easier to install.

It generates nwm.desktop, and has a script to start nwm inside xephyr.

./nwm init                #create nwm.desktop, and ~/.nwm/nwm-start
                              #this is called automatically by npm install
sudo ./nwm install    #move nwm.desktop to /usr/share/xsessions/
                              #will log to ~/.nwm/*.log
./nwm xephyr [size]  #start nwm in xephyr

It ended up uglier than I had hoped... because that is bash. I had some problems since node can't see sudo on my coniguration. but I've worked around it, hopefully in a way that will work for everyone.

Also, modified the scripts in the package.json so it would install for me, I had to cd build; make to get ./build/Release/nwm.node. I added this to scripts.postinstall

cheers,

Hi, thanks for this, but I'd prefer the installation to be done via actual packages for the specific OS, rather than bash scripts. The problem with bash is that it is hard to take into account the various environments, and if it breaks then it's easier for people to say "the installer is broken" vs "oh, maybe I need to check the path to node in the .desktop file".

I'm looking to target Ubuntu via .deb and Arch via AUR.

good point.
