Oliver Schramm 3d2c1b8f97 [ticket/15544] Delete cache through module manager
This might fix issues with migrations since the
sql cache will be purged as well. In general, this
puts all the logic in one place, so that's good.

* 2. The "automatic" way. For inserting multiple at a time based on the
* specs in the info file for the module(s). For this to work the
* modules must be correctly setup in the info file.
* An example follows (this would insert the settings, log, and flag
* modes from the includes/acp/info/acp_asacp.php file):
* array(
* 'module_basename' => 'asacp',
* 'modes' => array('settings', 'log', 'flag'),
