Qt signals

In guiqwt version 2, the signals module used to contain constants defining the custom Qt SIGNAL objects used by guiqwt: the signals definition were gathered there to avoid misspelling signals at connect and emit sites (with old-style signals, any misspelled signal string would have lead to a silent failure of signal emission or connection).

Since version 3, to ensure PyQt5 compatibility, guiqwt and thus plotpy are using only new-style signals and slots.

All signals are summarized below, in order to facilitate migration from guiqwt v2 to v3, then to plotpy.
