[PATCH] findbar: Hide when pressing Escape

[Vladimir Panteleev <git thecybershadow net>]

Connect a handler for the GTK stop-search signal, and hide the FindBar
when it is received.

Although there exists code in FileDiff.on_key_event to handle Escape
key presses, Escape key press events are not propagated when the
GtkSearchEntry has focus.
