B Crosstabs: Fix to wrong options hidden
Fix to nominal to scale variable conversion

If a nominal variable contained a floating point number, this was
erroneously converted to a missing value
Analyses: updates to variables allowed

A lot of analyses didn’t exclude NominalText variables where they
aren’t allowed - now they do.
Crosstabs: fix to occasional nulls in results
Tidy up

We no longer need to build JASP and JASPEngine separately with
different compilers on windows
Fix to JSON parsing locale issue 14,5
R: Added plotrix and logspline packages
Improved CSV auto detect + euro decimal handling

Fixes #79
Changed CSV delimiter detection to only determine the delimiter based
on the column names (the first row). This is such a simple and obvious
way to do it, I don’t know why I didn’t think of it in the first place.
Also adds support for european formatted numbers (with a comma for the
decimal place)
R: .clean() function now errors with bad input
Correlation: Added footnote to NaNs from Infinity

Closes #115
Descriptives: fix to formatting

Fixes #111
