Support Linting YAML as part of Travis CI build (#554) * add yamllint command to travis CI installs and runs a linter across the YAML in the project to ensure consistency in the written YAML. this uses yamllint and the default yamllint config with "truthy" and "line-length" disabled. * run dos2unix on CRLF files * YAMLLINT: remove trailing spaces * YAMLLint: add YAML document start * YAMLLint: too many spaces around bracket * YAMLLint: fix indentation * YAMLLint: remove duplicate key * YAMLLint: newline at end of file * YAMLLint: Too few spaces after comma * YAMLLint: too many spaces after colon
