Update personal user notes of a geocache
This method allows your users to to change the content of the user's personal note from one value to the other value.
We want you to know the previous value of the personal note, because we feel that your user needs to know what it is exactly that is going to be replaced.
Please note, that we do not require you to know - the old_value parameter is optional. However, if you don't provide it (or provide an obsolete value), then your new_value will be appended to the current personal note instead of replacing it.
Current personal user notes for the geocache can be retrieved using the my_notes field in the services/caches/geocache method.

Default value: (empty string)
The previous content of the note. (The content that you think that you are about to change.)
