Consistently use Obj-C boolean literals

[Keith Rollin]

There are places where we use equivalent but different expressions for Obj-C boolean objects. For example, we use both [NSNumber numberWithBool:YES] and @YES. There are places where both are used in the same function, such as -[WebPreferences initialize]. The boolean literal is in greater use and is more succinct, so standardize on that.

Nice!

Can we also translate these forms `@(YES)` => `@YES`:

Do we normally update webrtc sources? (Youenn would know)

Now that we've shortened these to just a few characters, I think we probably don't need to line them up. Looking at all the new features down below, those down have whitespace alignment.

Ugh these are just asking for @{} now!

Sure.

Probably not. I'll revert.

OK.

Yeah, I'm thinking of some follow-on patches. :-)
