Refactor createLi; add two new features with tests

[BaylorRae]

To start off, I really like your plugin. After looking through 2 or 3 different select dropdown plugins yours is by far my favorite.

---

I wanted to create a dropdown similar to YouTube's "Date Range" dropdown. It does two things that greatly improve the way the options are listed.

1. It adds separators to group the items
2. Options can have custom text added that isn't relevant to the option's text itself.

I don't know if it's something you want or not, but I added the Jasmine testing framework to hopefully prevent breaking existing functionality. If you don't like Jasmine, or using the jasmine-gem to run server, you can just grab the changes I made in bootstrap-select.js

Note: I didn't add a compressed version because I wasn't sure which compressor you liked.

How to use my changes

You can change the option's text by adding a data-option-text attribute. This option only applies to the dropdown menu itself. It doesn't modify the the text added to the button.

<select>
  <option value="week" data-option-text="This week <span>Sunday &ndash; today</span>">This week</option>
</select>

To add a separator you need to set data-separator to true. The value and text within then <option> tag is omitted.

<select>
  <option data-separator="true">---</option>
</select>

To style the separator I just added this to my code.

.dropdown-menu ul .separator {
  background: #ddd;
  height: 1px;
  display: block;
  margin: 5px 0;
}

That sounds good. If you want, I can try to add more tests for the rest of
the code when I get a chance.

Working on implementing these...

@caseyjhol I didn't see your comment, but it looks like you've got it implemented. I really like the api you used, it's much more descriptive. Thanks for adding my changes!
