Feature Request: Options

[markfaine]

Seems to be missing options for user configuration.

Options for linting based on usage:

1. Disable output (currently writes out files to ./temp folder, this isn't always desirable)
2. Ignore empty tags (might be there for a reason)
3. Allow specifying legacy document mode (X-UA-Compatible) it's still recommended if using bootstrap

Other options would also be helpful. See other HTML linters for ideas, for example:

• Line Endings (lf, crlf, false)
• quoting (single, double)
• indenting style (tabs/spaces, width)
• etc.
