2.11.0

CHANGES:

• atdpy: Support parametrized type definitions (#303)
• atdpy: Support options approximately by treating them as nullables (#320)
• atdts: Support parametrized type definitions (#303)
• atdts: Fix incorrect type for TypeScript readers/writers generated
  for type abstract.
• atdts: Fix incorrect type for TypeScript writers of optional fields.
  It was working only in special cases such as foo?: int.
• atdts: Eliminate the type alias type Int = number since it was
  more confusing than helpful. Occurrences of Int are replaced
  by number /*int*/.
• atdts: Disable all tslint and eslint rules in generated code so as
  to play well with all tslint and eslint configurations.
