Allow enabling/disabling of last name or city capitalization

[ArnaudHocevar]

By default, updating the profile from the WP dolibarr account page would trigger capitalization of last name and city. This is not a wished behavior, especially when it is not clearly documented.

Please allow setting an option to enable/disable automatic capitalization, as it creates a massive mess in the dolibarr database.

This behaviour will become the default in dolibarr's core in next version
but i work on a setting page for this and other things...
