Update FontAwesome 3.2.1 to 4.2.0

[kkirsche]

Hi Guys,

I have updated the version of FontAwesome used within Kibana from 3.2.1 to 4.2.0. This will allow for consistent upgrades. The most recent upgrade included a number of icons for graphs such as Line Chart, Pie Chart, etc. which I feel could be useful when asking the user for what type of chart they would like to use.

I would love to know what you think about this.

Sorry for the issue after Pull Request. I should have done this before.

We're using 4.2.0 in Kibana 4 now, in part because we wanted to use those chart type icons for chart selection.

No worries. I just saw that. That's the key icons that I saw that were beneficial. You fixed it. Submitting a pull request for a UI bug I found shortly.
