DECODE-URL is thrown off-track by certain characters in host/path

[rebolbot]

Submitted by: meijeru

See examples. A space in the host/path string functions as separator between host and path, whereas a ! sign is ignored together with all that follows.

>> decode-url to-url "ftp://a b"
== [scheme: 'ftp host: "a" path: " b"]
>> decode-url ftp://a!b
== [scheme: 'ftp host: "a"]
