Conditional xwd properties & project properties

[FayCross]

Some conditions for some page optional properties include looking at the value of properties at project level.

For example, in basicPages.xwd the disableGlossary option uses the condition "parent.glossary!=undefined" to check whether a glossary has been added at project level.

This condition will not work when the page is in a chapter as the parent is now the chapter and not the project.

@torinfo - I have had a look at the code in toolbox.js that deals with conditions but am struggling to work out how it works. It would be good to be able to use something like project.glossary which would always look at the project level data. Any ideas?

@FayCross I'll have a look at this. Should not be that difficult.
