* Add Wolfram Language as alias for Mathematica

Add "wl" and "wolframlang" as aliases for Mathematica.

In recent years, the language underpinning Mathematica has been called "Wolfram Language" (https://www.wolfram.com/language/)
and Mathematica is just the GUI application.

WL is a common abbreviation for Wolfram Language as well.

* Added spaces in Wolfram Language Aliases

Fixed Wolfram Language aliases to have a space so they can be automatically joined with relevant characters.
