MentorUserDictionaryPath should also be available in webconfig.ini
Currently, the MentorUserDictionaryPath property is only defined in serverconfig.ini, meaning the mgserver process is aware of user dictionaries.
However, webconfig.ini does not define such a property, nor does
MgInitializeWebTier look for this property in webconfig.ini
What this means is that outside of using the default
MENTOR_USER_DICTIONARY_PATH, the MapGuide Web Tier is not aware of any user dictionaries the MapGuide Server Tier would know about because there's no way to point both server and web tier to the same directory for user dictionaries.
