[bp/r50128][NEW]User wizard allows filling in the fields from the User Tracker (when defined) that are requested to new users upon registration. Useful for sites when  you want to request those new details to your users but they are registered already. This serves as the 'custom page' discussed weeks ago in the tikiwiki-devel list to allow your users to see custom information and request extra details for your users. It will be backported to 12.x after 12.1 is released. Not tested against all edge cases, but proven to work with the 'happy path' of the admin following the instructions in the admin wizard to apply the profile 'User Trakers' and follow the instructions therein.
[bp/r50139][NEW]Allow to define a different set of fields to be asked in the 'User Details' section of the User Wizard than the set of fields shown at Registration time for the Registered users. It will be backported to 12.x after 12.1 is released.
