Normalize prices to standard english notation using Zend_Locale_Math::normalize

[gavro]

When using non-english locales you can't save any values with decimals. Using a normalized english value whilst saving fixes this.

Front-end still works with as intended.

Looks like Zend_Locale_Math::normalize uses PHP's localeconv() function, which also defines the number of digits to the right of the decimal place (int_frac_digits and frac_digits) as 2. Will this override the BaseCurrencyPrecision value if it's set in the ShopConfig?

You might consider moving this logic into the Price class, since it's used in more than two places within the code.

Hmm, you're right about the localeconv() call. Will look into a different flow for that.

I've tried getting the logic into Price.php, but it seems whatever you set there (e.g. overriding setAmount/setValue), the EditForm logic (from the current controller) is still overriding the locale (and the value) at the last moment: Both Product & Variation have their own Amount() & Price() functions which might prevent any logic @ Price.php to persist ...?

Alrighty... Setting LC_NUMERIC to 'en_US' seems to do the trick. Setting the locale in PriceField/setValue() is working.
