Set UserAgent in casperjs

[kentr]

When using phantomjs, the UserAgent is set to the following in phantom.js

"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.17"

However, when using casperjs, the UserAgent is not set. casperjs uses its default value. On my system that is:

"Mozilla/5.0 (Macintosh; Intel Mac OS X) AppleWebKit/538.1 (KHTML, like Gecko) CasperJS/1.1.3+PhantomJS/2.1.1 Safari/538.1"

It is preferable for Wraith to use the same custom UserAgent with casperjs as it does with phantomjs as a baseline, to sidestep UserAgent blocking.
