appropriately capitalizes strings in table

- Changed strings in <code>getDayAbbrev</code> and <code>getMonthAbbrev</code> to Title Case:  <code>Array("JAN", "FEB", "MAR", "APR", "MAY"</code> to <code>Array("Jan", "Feb", "Mar", "Apr", "May"</code>
- Added a new Handlebars helper called "toTitleCase" which uses the function <code>toTitleCase()</code> to convert strings to ... wait for it ... title case. 

I adapted my code from https://gist.github.com/LeoDutra/2764339 which I referenced in a comment in the code.
