fixed 0029252: Session/LearningProgess/Timezone: Timezone issue (1h offset) with session title in "Learning Progress User Detail View"

28790, 26497, 25648 Rename showMoveIntoObjectTree to showPasteTree

When code was moved from the test GUI object in 27bebea7, a
necessary adaption of the target class was missed (`$this` now points to
another class).

Improve error propagation in ilServer (release_5-4)

Use the exit value of the JVM process to signal success or failure to
the caller.

It does not matter if System.exit throws a Throwable as a result of e.g.
super strict security rules; but for the usual case that it does not,
callers can easily react to errors.

Make initLogging properly signal to its caller when setting up logging
fails.

Its calling code, in handleRequest, is already prepared to handle errors
from logging inititalization. It makes not much sense to always return
“no error”.

This change structures the method like the others in the ilServer class.

Release 5.4 Bug Fixes Formula Question

Up until now ILIAS supported float tolerances in the Formula Question,
but the GUI cut off all decimal places and with subsequent changes to
the question could lead to a unintendet change of the tolerance.

The FormulaQuestion throws an uncatched error (division by 0) in case
"No Restrictions" are set for the "Result Type Selection". This was
fixed for "Fraction" and "Coprime Fraction" in commit
b9b74b66 and this solution is now
extended to "No Restrictions". This fix was adjusted though, because in
case of a ilMathDivisionByZeroException the users result was set to "0"
which might be a correct answer. Now the division by 0 lets the check
function return false, except in case the formula also threw this
exception.

fix #31628 MathJax: \ilMathJax::insertLatexImages results in an error when Mathjax is globally DISABLED

Has been introduced in 9fdcbe7a, but
wrongly named (file name contains a space character). An updated version
has been added with the proper name in
1f554266. This makes the former file
obsolete, and it should be purged from the tree.
