Form fields localization

[trendspotter]

CTS does not accept localized values in form fields. This is especially annoying in locales using comma as decimal separator. The application correctly populates the placeholder as eg 0,00 but then complains that the value is not a valid number and accepts only dot as a decimal separator.

Seems that form field localization needs to be explicitly enabled - https://docs.djangoproject.com/en/1.8/topics/forms/modelforms/#enabling-localization-of-fields
