[PLAYEXO] Uniform behavior of text formating for newlines

[nborie]

This could be a kind of bug report... As playexo is supposed to be reworked, I hope the dev will recall the following :heart:

In markdown, triple trailing white spaces produce a newline character. A line with just a triple white space forces a vertical space in the formatted html text. This avoid random html piece of <br /> in many places of exercises.

Currently, triple white spaces to newline works in introduction key of pltp files but does not work in text key in pl files. This is ugly, the behavior should be the same. Please set the same behavior for every human keys containing instructions devoted to other humans.

I vote to enable the triple white spaces to newline everywhere since it reduces language mixing. The documentation of the language of PLaTon should be as well updated with " Please use triple whites space instead of putting <br /> "

I.I.R.C., CC is supposed to rework playexo (and playactivity....). Please assign this ticket correctly.
