[BUG] Custom configuration is ignored and overridden about atom-beautify

[Glavin001]

Just got it working:

In the example above, it is for HTML.

Removed https://github.com/donaldpipowitch/atom-beautify/blob/45352dd90591826e72054536f671b9eb074a9843/lib/atom-beautify.js#L154-L156 because it was incorrectly merging all of the options together.

for (key in externalOptions) {
      _.merge(collectedConfig, externalOptions[key]);
}

Important: This will result in previous usage of nested configurations no longer merging, such as using the indent_size of js when applying to a HTML file.

I just noticed that the indent_char is being overridden to "" (empty string).

You can even see it in the screenshot in previous comments, final options versus the getOptions result in the console log.

The afflicting code is the cleanOptions:

function cleanOptions(data, types) {
  nopt.clean(data, types);
  return data;
}

Which really just calls https://github.com/npm/nopt

I am going to temporarily comment out the lines that use nopt, as it is definitely the issue.

Currently working on Handlebars support (see #13) and commenting it out makes everything work:

Before:

{{#if}}
{{#each}}
{{#if}}
content
{{/if}}
{{#if}}
content
{{/if}}
{{/each}}
{{/if}}

After (with nopt disabled):

{{#if}}
  {{#each}}
    {{#if}}
      content
    {{/if}}
    {{#if}}
      content
    {{/if}}
  {{/each}}
{{/if}}

See npm/nopt#38 (comment)

I have an object like the following:

{
  'indent_char': ' '
}

Where indent_char is a space character (' ').
After using nopt to clean, it is now an empty string, ''.
The same error occurs when using tab, '\t'.
Using underscore, '_', works as expected.
