loadScript has option to also create JSAPI css link tag(s)

How about getting the bootstrap method to also generate a CSS <link> tag when it creates the JS <script> tag? Could lead to fewer steps for consuming developers to have to remember to deal with.

Perhaps the options could be extended to include not only the JS url but also the CSS url? This would be helpful since the CSS url has different structures throughout the different incarnations of JSAPI 3.x and 4.x. Something like: options.cssUrl = 'https://js.arcgis.com/4.2/esri/css/main.css';

As of #163 most of the features discussed in this issue have been implemented. The remaining ones will be handled in new issues (like #157).

Or we could do some elegant thing w/ a css option that would replace includeCss and cssUrls:

• falsey means don’t do any css loading
• true means figure out default path based on version or url and include
• true plus theme: 'calcite' means figure out default path to theme and include that too
• an Array means load each as a url

If theme is supplied but css is falsey, theme is ignored.

I kind of like that better.
