Editor for java.net.URL, to directly populate a URL property instead of using a String property as bridge.

Supports Spring-style URL notation: any fully qualified standard URL ("file:", "http:", etc) and Spring's special "classpath:" pseudo-URL, as well as Spring's context-specific relative file paths.

Note: A URL must specify a valid protocol, else it will be rejected upfront. However, the target resource does not necessarily have to exist at the time of URL creation; this depends on the specific resource type.
