Important changes since 0.10:
	- Add more information about fault along the different agents. In
	particular, it allows a better error description for both local reasonner,
	and operator if needed.
	- Add support for complex computation in wait and assert.
	- Remove support for while, as it was never really used, and that it is now
	equivalent to wait with a 'complex' computation
	- Make hyperc a bit more start when handling arguments
	- Better handling of rpath so no more need to play with LD_LIBRARY_PATH
