contrib\imagecache.inc code

Issue Summary

Based on the fact that it is looking for 'action' as index to the passed array, I think the function install_imagecache_add_preset, line 30 needs to be changed from:

$action['data'] = $data;

to

$action['data'] = $data['data'];

Otherwise, the data does not get properly inserted into the table.

Also, as currently structured, the comment up top is incorrect: "Each action is itself an array with indexes of action, weight" ... it does not look for 'weight' index
