Constant penguin::DEFAULT_CONTROL_PATH

pub const DEFAULT_CONTROL_PATH: &str = "/~~penguin";

The URI path which is used for penguin internal control functions (e.g. opening WS connections).

We need a path that:

• is unlikely to clash with real paths of existing web applications,
• is still somewhat easy to type and remember (e.g. to send requests via curl), and
• doesn’t use any invalid or unsafe characters for URLs.

For URI paths, the characters a-z, A-Z, 0-9 and - . _ ~ are “safe”: they don’t need to be escaped and don’t have a special meaning.
