x_pageInfo now also holds any linkID and pageIDs

Also added 3 functions to help with page linking:

x_addPageLinks - processes the asfunction links to add page link functionality
x_navigateToPage - go to either page number, linkID or pageID
x_lookupPage - finds pageID or linkID in the pageInfo array and returns page number
