Expand PageSequenceMonitor Documentation

The documentation for PageSequenceMonitor is missing some helpful description on a couple parameters.

The table that lists "Page Sequence Parameter" options is really for the <page> element, and might benefit from a change to reference that fact.

For the Page Sequence Parameter:

• name: there is a visible note that should be removed from production.
• method: Is optional and defaults to GET
• user-info: Expected value is a colon-separated user/pass, such as username:password
• query: Missing description.  The value entered here will be concatenated to the path parameter with a ? to generate a proper URL encoding for the full URI.
• port: incomplete sentence
• There are a number of parameters with a "-" value in the Required field, indicating something other than required or optional.  These probably should be changed to optional
