YAMLException when vim swp file is present

[Jason Carpenter]

During a render, the following exception is thrown if estilo/palette/<colorscheme>.yml is open in vim and vim creates a estilo/palette/<colorscheme>.yml.swp file.

$> estilo render

/usr/lib/node_modules/estilo/node_modules/js-yaml/lib/js-yaml/loader.js:171
  throw generateError(state, message);
  ^

This may occur when other files are opened but I am still investigating this.

Tested with estilo version 1.3.3
