Search doesn't work

[aeonofdiscord]

Currently search services (like Veronica) don't do anything in ferret, because showing the search box is slightly complicated. I'm trying to figure out the best way to either:

• embed a uiEntry into a uiArea, or
• change the way page rendering works so each node is a separate uiControl

The second option is probably better, but comes with its own problems:

• uiArea is currently the only scrollable control, so I'd have to figure out a way to make uiBox scrollable
• uiBox can't change the colour of its own background, so it'd be the system default background colour (not a dealbreaker but kind of annoying)
• uiLabel doesn't support multiline text (though breaking lines up into separate uiLabels will probably work fine for now)

Search now works as of https://github.com/aeonofdiscord/ferret/commit/f90f90bff0903d5face0a8fcdc7ba00aeebf1684, although the UI flow isn't great.
