Add support for .distignore

[westonruter]

WP-CLI supports a .distignore file which is intended to be used in the release process. See https://github.com/wp-cli/scaffold-command/blob/master/templates/plugin-distignore.mustache

It would be be handy if grunt-wp-deploy could read from these files when building the file list, if for example a build directory was not supplied in the Gruntfile.

There's also a .gitattributes file that's commonly used to ignore files from a package.

I don't think file ignorance should be the responsibility of this package. The build process should take care of copying the desired files into the build directory.

I'm using the gitattributes-globs package from NPM to automatically ignore files in my .gitignore file, I'm pretty sure it works for the .distignore syntax too.

Sorry, I missed this ticket when originally posted. I'm inclined to agree with John here, this package was only intended to be a wrapper for SVN to make deploying a finished build to WP.org easier. The build folder should be the finished artifact.
