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

use JsonRestStore instead of ItemFileReadStore, this will be required for the upcoming lazy load (plugins)

it doesn't really make sense to do not generate menu on every request, disable it for now
