Spintax 1.2.0

Changed

• The syntax no longer claims the .gtw extension; it applies to .spintax only.
  .gtw belongs to Generating The Web — the 2009 application this syntax was
  originally based on — and is a container format rather than raw template text,
  so highlighting it as spintax was wrong. The Modern Spintax Engine has its own
  standard, and .spintax is its canonical extension.
• README drops the remaining GTW wording and names the Modern Spintax Engine
  (@spintax/core) as the contract the grammar mirrors.

Fixed

• README rendered incorrectly on packagecontrol.io: the construct table was cut
  off at the first | inside each example (escaped pipes are not honoured there),
  and the spintax code fence raised language not supported. The table is now a
  list and the fence is untagged, so every example shows in full.

Documentation

• Document the empty enumeration option ({|a|b}) and the bare permutation form
  ([a|b|c]) alongside the configured one.
