Improved name param processing for gulp task `component`

[thematho]

This pull request contains updates for the cap function in the gulp component task. Now we can create components with names containing - and _.

Example: Running: npm run component -- --name my-component Will generate:

/client/app/components/my-component
/client/app/components/my-component/my-component.component.js
/client/app/components/my-component/my-component.controller.js
/client/app/components/my-component/my-component.html
/client/app/components/my-component/my-component.js
/client/app/components/my-component/my-component.scss
/client/app/components/my-component/my-component.spec.js

And the controller name will be:

class MyComponentController {
  constructor() {
    this.name = 'myComponent';
  }
}

export default MyComponentController;

Changelog:

• Updated cap function to manage names with "-" and "_".
• Updated temp files to use camelCase instead of upCase.
• Updated CSS selector to match component instead of class.
• Updated Readme

thanks, @thematho.

How do you think, should we leave usage of gulp component or maybe it would be better to use special code generation tools like plop? I already prepared #191 which also handles naming.

@fesor Thanks for your comment, I think plop is much better so I'll discharge this pull request. I'm going to merge your branch with mine, and add some features like service, factory and ngMocks generators. when your pull request gets merged I'll send another one.

Regards.
