By checking on the "Show Descendents" checkbox when adding a Children Display macro, it will display all descendents on a page. Even this behavior is described in the Children Display macro's documentation, this can be still pretty confusing when we want to control the "Depth of Descendents" option. Setting any value for the "Depth of Descendents" option is not reflect the real display when the "Show Descendents" option is being checked.

Parameter	Description
Show Descendants (all)	... If true shows the complete tree of pages underneath the parent page, regardless of Depth of Descendants

Proposal for preventing this confusion:

1. Rename select box "Show Descendants" to "Show All Descendants"
2. Move "Depth of Descendants" up so that it is right after "Show All Descendants" and when "Show All Descendants" is selected grey out OR better hide "Depth of Descendants" field
