Ability to import settings from the geek panel

After installing ContentBox, the administrator needs to add several settings to ContentBox. These will be stored in the database in the table "cb_setting"

Some settings are generic, which might be equal to other ContentBox sites.
e.g. The settings of the mail server is equal on all sites.

It would be very useful, to have the possibilty to export the settings of a site and import these settings to a fresh installation.

This would simplify and speed up an new installation perfectly.
