oops, forgot the translated files
unify and reword the strings to translate
retranslate the engine to french
that lib is not used anymore
to get translations, I need that import
increase a bit the window size (so that french title fits)
check whether python & scala are usable before doing so. This will allow stripped jars
identica is gone a while ago
remove our prototypal jabber dialog box. This was not used as a slower forum would be more adapted
we don't need a dist-src target: we have a .gitattributes file
Build a plm-light jarfile, without scala and python dependencies.

These langs remain usable if the deps are independently installed.
get plm.major.version from the properties file and use it in the jar filenames
retranslate fully the engine to french
don't switch to python by default if python is wrongly installed
dependency searching mechanism made robust for when we start from a jarfile
Release 2.2. The funny times are over.

  * Change the program name: JLM -> PLM (Programmer's Learning Machine)
  * Turtles: Allow for hints on segment sizes
  * Turtle.circle(): New primitive to draw circles directly.
  * New lesson turtleart on the classical Logo geometric figures
  * Upgrade our twitter4j dependency to use the new twitter API 1.1
    Twitter dropped support for the 1.0 API a while ago.
  * Drop the identi.ca spy. It does not work since the upstream move
    from status.net to pump.io, and I fail fixing it.
  * Drop our prototypal jabber chat dialog. It was not activated
    because it's not adapted: student only use it to try to cheat and
    get easy answers. A forum would be better. Students are
    authenticated, and the messages moderated (France IOI does that)
  * Build a plm-light jarfile, without scala and python dependencies.
    These langs remain usable if the deps are independently installed.
  * Specify a sain font as default to help Mac users (fix #100)
