With this checkin, ender-based gfx rendered text controls now work properly both as HTML text controls and XUL text fields.
GFX text controls are not enabled by default. The primary goal of the next few days is to stabilize the tree, so I thought it would be inappropriate to enable the new feature by default. But you can still set your nglayout.widget.mode pref to enable them. Here's what I did: 1) backed out a small part of Simon & Kin's fix to nsGFXTextControlFrame that was mistakenly setting up the text control's webshell as a frame. It still (correctly) isn't doing that, but it does not set the webshell's prefs from the outer webshell. 2) for output, I now ask for format="text/plain" rather than "text/html", since (for now) these are all plain text edit controls. Soon, this will depend on the type of edit control 3) fixed some ownership issues between the frame, the editor, and the subdocument being edited. This fixes an assertion on dialog destruction if the dialog included a GFX-rendered text widget, and some memory leaks. 4) set up DOM key listeners on the editor to propogate events from the editor to the parent document, so things like form submission on Enter, and onKeyUp handlers work. More work is needed here for other kinds of events.
