Start port of zed

zed -d path/to/zed.d -p path/to/pid.txt -s path/to/zed.state -f

Add simple zedlet and support functions

Add all-debug.ps1 example, which uses
zed-function.ps1 to post Notification on
events.

More work needed, in particular to make scripts run
in the background rather than being waited upon.
