For express mode:
- Move the search bar up to the toolbar.
- Hide the "filter" combo box and lock down the first item.
- Hide the "scope" combo box and lock down the first item.
(This is the combo box with "Current Folder" only in the mailer.)
- EShellView owns the search bar widget now instead of EShellContent.
- Insert several nasty hacks that will likely come back to bite me.
Move the search interface to a new widget: EShellSearchbar
The current search rule is now stored in EShellView, and the search
context in EShellViewClass similar to GalViewCollection (since it's
class-specific, not instance-specific).
Also add a couple new signals to EShellView: "clear-search" and
"custom-search" ("custom" refers to an advanced search or a saved
search -- something more complex than a quick search).
Still working out a few kinks. The search entry is clearly trying to
be too many things. We need a different way of indicating that you're
looking at search results. Perhaps a search results banner similar to
Nautilus.
