qcli panel activation/deactivation

[JeromeMartinez]

Panels can currently be activated only through the GUI, preventing configuration from the CLI only (without the GUI installed).
This patch adds panel activation/deactivation through the CLI.

-show-panels
    Show the available panels.
    First column is an index to be used with -activate-panel or -deactivate-panel.
    Second column is the status of the panel ("active" if the panel is used during analysis).
    Third column is the name of the panel
-activate-panel <panel name or index>
    Register the panel as active.
    Use "all" panel name for registering all panels as active.
-deactivate-panel <panel name or index>
    Register the panel as not active.
    Use "all" panel name for registering all panels as not active.
