Improve taxonomy parser to handle commas that are part of entry names

[stephanegigandet]

e.g. for Open Beauty Facts, we have chemicals with formulas like:

5-Bromo-5-Nitro-1,3 Dioxane

Currently commas are considered separators:

1. in the taxonomy definition (synonyms are separated by commas and optionaly spaces)
2. in the fields (e.g. categories) entry

[stephanegigandet]

Proposed solution (currently live on http://world.openbeautyfacts.org): do not treat commas as separators if they are between 2 digits.

replace by a lower comma ‚
$line =~ s/(\d),(\d)/$1‚$2/g;

Need to check if this covers all the cases of names that contain commas, and if there are cases where commas between 2 digits should indeed be treated as separators.

I didn't have time to work on it. It is something we'll probably need to do eventually, but currently it is not high in terms of priority.
