Subject: [PATCH] Initialize Mathematica language

Language initialization can cause error when done after executing
`\FV@FormattingPrep` command from `fancyvrb` package. This can happen
inside `\mmaInlineCell`, if it's used without previous language
initialization.

Proper initialization happens e.g. inside `mmaCell` environment so it's
easy to miss this problem.

To fix it, we simply initialize language inside package.
