(ham/predict) Updated to 2.2.6

Release 2.2.6:
By John A. Magliacane <kd2bd@amsat.org> (20-May-2020):

* The installer program has been replaced by a bash script that
  configures, compiles, and installs PREDICT and several companion
    client utility applications.

* The SingleTrack and MultiTrack displays have been modified for
  more consistent performance across a wider range of terminals.

* PREDICT's "vocalizer" now employs the Advanced Linux Sound
  Architecture (ALSA) environment instead of OSS in response
    to recent changes in v5.6 and later Linux kernels.

* The handling of geosynchronous and geostationary satellites
  has been improved, but still needs to be used with caution.

* 100 MHz normalized downlink Doppler shift information has been
  added to all -p and -f command-line outputs.

* The documentation and the transponder database file have been
  updated, and the format of the man page has been corrected.
