Build machine details, mode, and trustedness should be edited on the same page

[Matthew Paul Thomas]

The page for changing a build machine's mode (+mode), the page for changing all the machine's other details if you aren't an admin (+edit), and the page for changing all the machine's details if you are an admin (+admin), should all be the same page. Things you don't have permission to change should be shown but unclickable.

I'm not against, but I'm not sure about the form format.
Long forms with text box tends to induce errors. Maybe we can cover description and failnotes fields with the fieldset tag. What do you think ?

[Matthew Paul Thomas (mpt)]

Implementation of the FormLayout spec will make the form much shorter. Even now, the <textareas> are too long and many of the captions are unnecessary.

[Michael Nelson (michael.nelson)]

During a chat with Julian and Celso, we decided to merge +admin and +edit, but put form for editing the mode directly on the builder-index page (it will post to the normal url and redirect back to the builder-index, obviously only being visible/functional to those with the correct permission).

Also, we can't even see any reason for the edit/admin distinction.
