Added the ability to update a wildcard domain `*` and pass multiple domains in one call

## Wild Card Domains
I have applied a fix that enables dynroute to update wildcard domains.
The bug was being caused by Route53 accepting `*` but when returning the zone list it would be encoded as `\052`

## Pass Multiple Domains
You can now pass multiple domains to dynroute in a single call.

`dynroute -d foo.com -d bar.com`
