v0.1.5

Added

• paginate.step, how much {page} advances between pages.
• require on an item list, naming further fields a row cannot do without.
• A strip_matching step, removing an element whose text matches a pattern.
• check_response and login are called.

Fixed

• A pipe naming a step that does not exist passed validation.
• A require naming an undeclared field is refused at load time.
• The JSON Schema rejected the null that deletes an inherited key.
• A pipe fed by all: true was type-checked as though it took a scalar.

Changed

• spec increments on a change in meaning, not on an addition.
