Improve handling of version flag
* Only use/show builtin `--version` flag if args are versioned with a non-empty `Version()`
* If args define a `--version` flag, honor it and disable/hide the builtin version flag
* Only return `ErrVersion` when using the builtin version flag

Dylan Allbee 5df19ebe00 Use command passed into p.Parse(...) write methods
It is currently impossible to programatically write help and usage
messages for subcommands, due to parser.WriteHelp and parser.WriteUsage
not taking the state of the parser into account.

Check for the existence of p.lastCmd and use it for the writers when
available.

Enables ability to write unit tests for subcommand help.

Print defaults for multiples
Check if the default value supplied is a slice and not nil, if so
print the list of values supplied.
Test case for slice argument with and without default values.
Default values for slices was not printed because slice is not
comparable, but the zero value for slices is nil.
