Fixed no rf-gate w/o digi bug

Turns out that when configured as an I-gate and NOT as a digipeater,
aprx didn't add any heard stations to the historydb, since the receiver
wasn't a source for the transmitter. This made being an implicit RF-gate
without being a digipeater impossible.

Converted make-deb from SVN to GIT

* beacon.c:

    Limit read amount of 256 bytes, excess is rejected and usually
    also the beaconing is skipped.

* config.c:

    Clean away some superflous debugs.
* digipeater.c:
    Viscous mode debug printout crashes on SEGV.. Oops.
    (without debug the bug does not hit.)
