display the mission in all progLangs when in debug mode
s/turnLeft/left/ in the button of the buggle panel, too
allow [!java]...[/!] constructs in mission texts (+easier debug)

This is a lighter way to adapt the mission text to the current
programming language.

Also, if you are in debugging mode, the text of all programming
languages is displayed with a color code to see all in one try.
port the first three exercises of the welcome lesson to scala
also translate the builtins of buggles and turtles in their universe documentation
add two new markup commands to our 'html' filter
scalaize the exercise on conditionnals.

That becomes hairly with 3 programming languages and 2 human
languages, but the new wiki-like syntax really helps.
mention to the students that they have to unfold the tree to see all exercises
Allow the SKEL chunk to appear at the end of file, too
don't redefine the entity in scala to please eclipse

Actually, that's a false positive as we never compile this file
directly, and the class name gets rewritten when used at run time.
shorten this solution -- I copy/paste it quite often after all
only display the compiled python script when we get an exception
allow to mess with the correction field of source files after their creation
cosmetics
cosmetics: translate strings, and don't silently fail on error
make sure that JUnit on java compiling works for Bat exercises too
do not save sessions during regression tests. Speeds up the process by ~ one third
remove stuff from ExerciseTemplatingEntities skeletons so that we can generate an entity code that compiles in both java and scala
show the compiled source when an compilation error occures
an error message was inverted
