View Results Tree: Response Data->Response Body is illegible with Darcula theme

**Brian Tully** ([Bug 64224](https://bz.apache.org/bugzilla//show_bug.cgi?id=64224&redirect=false)):
For the past several major releases of JMeter, I've found that the Darcula theme is much easier on the eyes when using the GUI. However one glaring issue that still exists is the fact that in the View Results Tree listener, the Response Body content is unreadable since it puts dark text on a dark background. This occurs on the Text, HTML, and HTML Source Formatted view options. I've attached a screenshot to illustrate the issue.

Note that the Response headers tab displays content appropriately, i.e., there is a dark background, there is also a left margin with line numbers, but the content has light colored text on a dark background, so is legible. Ideally both the Response Body and Response headers tabs would use the same theme/styling, so that both tabs' content were legible.
