Issue #177: parsing of decimal in formula (dismine/valentina)

New issue 177: parsing of decimal in formula https://bitbucket.org/valentinateam/valentina/issue/177/parsing-of-decimal-in-formula

MitSchoko:

Can not enter decimal number in formula.

On My Ubuntu ( german localization while my qtcreator has englisch localization) neither i.e. 3,4 (official german notation for decimals) nor 3.4 can be parsed.

Formulas from existing file work fine.

The debug console says:

Message: "Unexpected token “.4 " found at position 10.” Expression: "Name_1 / 3.4 "

Formulas should accept only 3.4 notation (or both notations) in m.h.o.
