Announcing Flent v0.12.2.

[Toke Høiland-Jørgensen]

This is to announce v0.12.2 of Flent: The FLExible Network Tester.

Flent can be installed via pip by issuing pip install flent, or on Arch
Linux through the AUR. Pre-built packages are available for Debian and
Ubuntu at
https://software.opensuse.org/download.html?project=home:tohojo:flent&package=flent.

This release includes a major refactoring of the plotting code, which
should make it easier to extend in the future. Please report any
regressions as bugs.

Other changes since v0.11.1:

* GUI restructuring: The plot settings now reside in a menu, the
  metadata view defaults to the bottom part of the window, and a new
  open files view has been added to make it easier to manage many open
  files at once in the GUI.

* Revert to writing data files to the current directory by default. A
  new parameter, -D, can optionally select a different output dir.

* The man page is now generated from the Sphinx documentation.

* Try to detect if the system `ping` utility produces parsable output
  before using it. Should give nicer error messages on OSX if fping is
  not installed.

* Add a new qdisc-stats test which will periodically gather qdisc
  statistics and a wlan-retries test which will gather WiFi retry
  statistics.

* New tests comparing different TCP congestion control algorithms have
  been added.

* Add a --replace-legend parameter to do search/replace on legends when
  plotting.

* A test suite has been added containing basic unittests for parts of
  the code. Test coverage is still fairly poor, but will be extended
  going forward. Run `make test` to run the test suite (requires the
  'mock' Python library).

* VoIP tests can now show loss rates.

* A bunch of bug fixes.
