Provide a Command line tool that generates a Field Type skeleton

php ezpublish/console ez:generate:fieldtype

Options:

• Field Type name & identifier

Bonus options:

• external data, y/n
• legacy: requires external tables

Generated items

Depending on the answers, the items of a FieldType are generated for the base files in a custom bundle:

• Value & Type
• YUI field edit & view files (templates + configuration ?)
• Repository-forms FieldDefinition and FieldValue form mappers, and fieldsettings template
• FieldDefinition & FieldValue twig templates + configuration
• SearchField (need doc & research)
• If external data, Storage class +

Generated documentation

An interesting extra feature would be to generate a markdown file at the root of the bundle, with a walkthrough of the generated files & code, with clickable links to the generated files.
