FreeNAS Code

several changes to the treemenu so we can support hook of plugin items

- change attribute of url path to pen from "view" to "url"
- change the gname attribute so it is autogenerated from the position of the tree
- e.g. UPS node under Services is called "services.UPS"
- add a simple method to catch new items from an url (plugin)
- the url must return a JSON array containing nodes for the tree
- the node can be appended anywhere in the tree:
- e.g. "append_to": "services.Rsync.RsyncMod" will append it to Rsync Modules node
- split auto_generate in two
- prepare_modelforms go through all the models and find all related modelforms
- generate actually generate the menu structures to dump as JSON later on

Follow up r8093 by correcting the grammar for "Sysctls".
