[balsa] balsa-message: Connect to "search-changed" signal

commit fb795d4824e62d827f9637eab4ba77c77b4be1ed

    balsa-message: Connect to "search-changed" signal
    
    Connect to GtkSearchEntry's "search-changed" signal instead of
    GtkEditable's "changed" signal; it provides a 150 msec delay: "To make
    filtering appear more reactive, it is a good idea to not react to every
    change in the entry text immediately, but only after a short delay. To
    support this, GtkSearchEntry emits the “search-changed” signal which
    can be used instead of the “changed” signal."
    
    * src/balsa-message.c (bm_find_bar_new): connect to
      GtkSearchEntry's "search-changed" signal instead of GtkEditable's
      "changed" signal
