v3.0.0

• Support for repeatable fields and repeatable group fields! Props @AlchemyUnited & @erangalp
• Update Select2 to from 3.5.1 to 4.0.2
• The asset path is now filterable. If you choose to include this field type within a theme/plugin, you can now override the location of front end scripts/styles
• Placeholder text can now be defined separately from the field description
• Documentation update, including updated examples
• The major version bump is due to a slight change in behaviour. Previously when using a multi-value select field, any saved values which no longer exist in the options array, even though they're not visible, the values would have remained when saved. Now, upon saving, these orphaned values are discarded. Props @gyrus
