Add Equalizer and Phase + Freq. correction to QPKS simulation

Continuing the work of commit 20e54b3cf198f17e05a3c7e8716138717447aa32

Important:

  - The diagram has been updated to include a CMA equalizer and a costas
    loop (for phase correction and small frequency correction).

TODO:

  - Decode the signal

  - Create USRP hardware sinks (RX side, for later)

    It would be very nice if we manage to find a 'switch' block that
    allows to have in a single flow diagram both the simulated and
    "real" signals.

    NOTE: recall that the USRP gives directly a baseband signal, which
    means that everything between the channel the costas loop (both
    included) will not be used when the hardware is connected. Only the
    (not yet) implemented decoder (and eventually some more filters if
    needed) will be used.

Other notes:

  - The layout has been updated to use QT Tab widgets (defined on the
    top left corner). GUI elements can be put into tabs by giving a
    string '<tab name>@<tab nr>: <grid options>' as GUI hint.

  - To make the diagram nicer, all GUI sinks (eg. constellations plots
    of time / freq. plots) are vertically aligned. Constellation above,
    and time and freq. sinks below. Variables ought to be placed near
    their respective block, unless they are global, in which case they
    should go on the top left.
