Need at least to line changes to work under 4.7

1) format_name()
format_name() → theme('username'): minor required change.
See: http://drupal.org/node/22218

2) array2object
array2object moderately used: replace by native PHP conversion
See: http://drupal.org/node/22218

I made these to changes on my copy and the site menu loaded just fine.

Thanks,
Christophe D
