This allows Travis to use their new container-based infrastructure,
which should speed up the builds.

Fix duplicate vow name

The new lexer was merged from PR made in jashkenas/coffeescript#3770

Also closes #372

no_unnecessary_double_quotes

- Removed Block RegExp Fix that was originally patched in PR #340.
  Thanks to the new PR, this is no longer needed
- Shortened function name `containsSingleQuote` to `hasSingleQuote`
- Changed how we detect if we're inside an interpolated string to be
  more like the way we handle interpolation in space_operators

no_trailing_semicolons rule

- Due to the new way tokens are generated, we now check for 'STRING_END'
  token rather than a 'CALL_END' token

space_operators

- Removed old code that assumed an interpolated string always begins
  with empty quotes. Due to new changes in CoffeeScript lexer, we can
  now use 'STRING_START' to determine the beginning of an interpolated
  string
- Renamed lintParens, lintCall to trackParens, trackCall respectively

This was caused because class declarations generate a brace so this
changes it to ignore the first implied brace, but take into account any
future implied braces

Fixes #324

Renamed test_braces.coffee to test_no_implicit_braces.coffee

Update to CoffeeScript 1.9.1

braces_padding

Fix no_implicit_braces error in class declarations

Add node v0.12 and iojs to travis.yml file for testing.
