Improve user export

[msquare]

There are a few things with the user export function that can be improved.

My ideas are:

1. The export is located under "FRAB import and export". FRAB is a system to manage events and has nothing to do with users. Restore this to "Frab import" and locate the export button on top of the users list (users_list_controller() and Users_view()).
2. The export writes a file to the file system. This can lead to problems because not all environments allow this and because userdata including hashes is written to the filesystems tmp dir - and every server user can read this.
3. Exclude password hashes from export!
4. Make sure to put CSV content into a .csv file (not .xls) - I think this is already fixed.
5. Move the code to a users_export function in the users_controller.php for this feature
