init: Allow wildcards in property triggers by using * for property value
For example, the following trigger will fire when the sys.foo property
is set to any value:
on property:sys.foo=*
write /data/foo hello
It is also possible to refer to the property within the trigger actions:
on property:sys.foo=*
write /data/foo $sys.foo
