Added composer.json
Initial Price FieldType implementation

Bundle structure + Basic Type + Value + Template + Configuration
Implemented Legacy Converter
Added Legacy Price Converter test + test structure
Added base view template for showing price
Added price unit & SPI tests
Removed test duplicate
Cleaned up Price\Value

Now has two properties: (float)$price and (bool)$isVatIncluded.

hash & persistence handling have been updated.
The Converter now reads data_text, formatted as "<isVatIncluded>,<vatId>",
and sets the appropriate value.

The Value constructor now accepts, for convenience:
- either an array of properties,
- or a price.

The test was wrong, and was passing an array instead of a Price\Value. This changes this, and updates the implementation accordingly.
