Subject: [PATCH] Another approach to fix duplicates - priorities

Priority description: (lower number - higher priority)
1-99 Highest priority - overrides everything, even pages from database, use with caption
100 - default for pages in database
101-999 - recommended range for plugins
1000 - default value for plugins if no other specified
1001 - 9999 - no usage currently
10000 - default myaac routes
