Meta-schema exclusive* and default string array

Change the exclusiveMinimum|Maximum (and the one usage within the
meta-schema) to allow numbers.  Remove the default as the boolean
form is a SHOULD NOT and there is no default for numeric limits.
Add "examples", which I apparently forgot to do when I did the spec
change.

Also default string arrays to the empty array.
