Added multiple backends support for Customer companies (Cyrille Bol)
Fixed some bugs from previous commit:

  1- Fixed some typos and small errors that prevented the previous commit to actually work.
  2- Since I had copied the CustomerCompany/DB.pm file from the CustomerUser/DB.pm file, I had forgot to remove some reference to CustomerUser related variables. This is now fixed.
  3- I had forgot to implement the search filter in the CustomerCompanyList function. So, the Customer Company list was never filtered. This is now fixed.

Made adaptation requested by Martin Gruner to my patch for adding multiple backends support to CustomerCompany:

  1- Added a Module line to the CustomerCompany default config in Default.pm (+ Added a Name line)
  2- Added fallback in CustomerCompany.pm for people migrating from 3.2 which have this setting not set in their config
  3- Added a dropdown list to the AdminCustomerCompany module to show the writeable sources where Customer companies can be added.
