Closed #113 Update module
Closed #105 Add module.config.php for custom modules
Closed #116 Bug ActivityLog Module

Add method for update module, if you have custom module, in your
Module.php file, add update method with $latestVersion as string
parameter. This will be execute after upgrade method.

Modules are now loaded with Zend\ModuleManager\ModuleManager, so you can
add config file with method getconfig, and execute some code on
bootstrap with onBoostrap method like Zend Framework 2 ModuleSkeletton.
But you will not be able to load controller or router (curently).

New activityLog template will be added to fix the bug. GetParam method
with user as parameter will return AdminUser::getName or ip address.
