Setting init script defaults

The default init script doesn't mention the kiosk at all. Since thats
what this app is it makes sense to have some level of tie in.
Use usr/local

Didn't mean to change that bit of the path
Supports not backgrounding

Although the short help doesn't mention it turns out you can run the
script without backgrounding.
Adding Readme file with discoveries so far

This point took a bit of work to acheive (not helped by nodejs packages
being hard to find)
Specify version for express

failing to do this results in a white screen of boringness rather then a
big green screen of joy.
Uppercase readme

Because its traditional to have README in shouty caps.
Tidy up readme for submission

I'll be pushing this live somewhere so i can request a merge soon so
having the readme looking remotely respectable will be required.
Fix path for DAEMON_ARGS

Looks like when i fixed my first mistake i typo'd the path
Readme was renamed to README

Not sure why this wasn't removed as part of that commit
