v0.30.0

• When the clean_accents option is enabled for entry slugs, certain characters, such as German umlauts, will now be transliterated. This effectively solves decaporg/decap-cms#1685.
• The default value for the hidden widget now supports the {{locale}} and {{datetime}} template tags, which will be replaced by the locale code and the current date/time in ISO 8601 format, respectively. This effectively solves decaporg/decap-cms#5969 and decaporg/decap-cms#1270.
• Any links to other entries will now work as expected, with the Content Editor being updated for the other. This effectively solves decaporg/decap-cms#4147.
