EDAstro plugin ignores the "Send data to EDAstro" setting

[rinkulu]

# plugins/edastro_core.py
    if this.log and entry["event"] in ["CarrierStats", "CarrierJumpRequest", "ScanOrganic"]:
        edastro_update(system, entry, state)

this.log is tk.IntVar; its underlying value must be checked with this.log.get(). Right now this condition always passes, effectively ignoring the disabled state of the option, so the data always gets sent.
