DevEnv: add-brackets in astylerc set to true

[Rohan-Dah]

As per the style guide https://ardupilot.org/dev/docs/style-guide.html , control statements (if, while, do, else) should always use braces around the statements. This can be implemented by setting add-brackets option to true.

Isn't that implicit?

I mean, if not, the line above would seem to suffer the same problem.
