Now that ProB supports reals, an expression like x>y is no longer
sufficient to infer that x and y are integers.

LaTeX formulas inside tables cause various layout issues in Jupyter
Notebook, such as long sets being wrapped even when they would fit on a
single line, table columns being wider than necessary, and LaTeX
formulas being left-aligned instead of right-aligned like normal text.

In some cases, ProB apparently "unwraps" LET predicates as well,
not just existential quantifications.

Event-B/Rodin does not support LET like ProB does, so we need to use
some workarounds to provide similar functionality in Event-B mode.

This matches what almost all code already did anyway. It will also help
with fixing the problems with local variables in Event-B mode - the fix
will require conditionally parsing multiple formulas.

ProB 2 now always throws ProBError for parse errors and
ModelTranslationError is no longer used.

The Gradle documentation says that these convention properties are
deprecated and superseded by the java and application extension blocks.
Using the convention properties doesn't generate warnings yet, but it
can't hurt to switch to the now recommended way.
