Degree of certainty code checks for French terms

In the code for the Degree of Certainty questions, there's a check on "ensemble" and "résultat" to resize the text. This is a very bad and non-portable idea 😉. What about simply checking for the size of the whole string and reduce it if it is larger than a length of 80 or 100 characters, instead?

See:

chamilo-lms/main/exercise/MultipleAnswerTrueFalseDegreeCertainty.php

Lines 716 to 717 in 6ff87c3

	strpos($title, 'ensemble') > 0 ||
	strpos($title, 'votre dernier résultat à ce test') > 0

For what I could see, this code (hardcoded French strings) wasn't even used, so I removed it.
