Replace ugly JS_Define macros with templates.
This allows us to step through the JS bindings code with the debugger, which I could not do (but wanted to) the other day. In the process, get rid of some else after returns, and one unreachable code path. I also get rid of some tracing macros that we would never use for the sake of clarity, and some plain unused definitions.
