Added a new parameter, bookmarks.collapse, that controls the initial state

of the bookmark tree. When the parameter has a non-zero value (the default),
only the top-level bookmarks are displayed initially. Otherwise, the whole
tree of bookmarks is displayed.

This is implemented for FOP 0.9X. Closes FR #1792326.
