GTK: Implement GtkFloatingContainer and implement StatusBubble on top of it.

This introduces a hybrid GtkBin/GtkFixed container which exposes a signal to absolutely position widgets. This also fixes the current flickering issues with the status bubble.

TEST=Goto a site with a long list of links (I used reddit.com) and move the mouse cursor up and down the list quickly. There shouldn't be flickering in the top left corner.
