Text Annotation Tool: Safari Colored Highlights Bug Fix

**Background:** Forgot to close a set of Parentheses and it is causing CSS inconsistencies between Safari and the rest of the browsers.

**Studio Updates:** None.

**LMS Updates:** Literally added a parenthesis. It will now allow tagging to change the color of the highlighted annotations in Safari.

**Testing:** Set up the text annotation component in Advanced Settings under "advanced_modules." Add the component to a Unit and head over to the LMS and add an annotation. Make sure to add a tag with a color (defaults to "imagery" being red and "parallelism" being blue). Before if you did that in Safari, it would stay yellow. 
I might recommend making this spacing better so that future bugs are easier to spot. That is, try this:

```javascript
$(annotations[annNum]).css(
    "background",
    // Colors should be wrapped with ", but the final value must be a number
    "rgba(" + finalcolor.red + ", " + finalcolor.green + ", " + finalcolor.blue + ", 0.3)"
);
```
