• Adds DartSassFilter for Dart Sass Support

• Adds debug_level option for working with error handers

Removes Locked Dependencies

Removes the composer.lock from the repo.

Configurable Prefixes

Using three new methods in PleasingPrefixFilter, one can now configure which prefixes are added to to which properties and values.

The methods are:

• setPrefixProperties: Prefixes for properties that should be prefixed.
• setPrefixValues: Prefixes for values in properties where the value is prefixed.
• setUsePreconfigured: Toggle for using the built in prefix configuration. Default of TRUE.

No changes are needed unless you wish to configure which prefixes are used.

Additional Intrinsic Sizing Prefixes

Adds intrinsic sizing prefixes for height. Note that these may not work in some versions of Firefox due to a limitation in those browsers.

Adds Basic Grid Support

Adds basic support for CSS grid & Internet Explorer. Note that this version requires writing VERY IE-friendly SCSS. No support for auto-placement, grid-gap, auto-fit, start/end syntax in grid-column/row -- just prefixes.
