Added option for Gulp logging

[haydenbleasel]

Typically Gulp plugins suppress the output of the native module and add an option to log the output. Basically:

.pipe(bless({
  log: true
}));

Gives the option of keeping the command line clean.

Couldn't this just be if (options.log) {?

[haydenbleasel]

Generally yes but for options I'm making it specific to avoid people getting true when entering 1, !0, !null, etc. Check this out for some interesting reading: http://dorey.github.io/JavaScript-Equality-Table/

[adam-lynch]

!0 and !null are === true. Sure 1 isn't === true but why restrict it? Let's allow them to pass any "truthy" value to turn on logging.

[adam-lynch]

The README would need to change. E.g. lines like this:

bless(options). The (optional) options argument is passed on as is to bless.js.

Maybe we should also say it defaults to false.

Do you know if this is testable?

[haydenbleasel]

Not sure if it's unit testable but I have tested it manually. It's a fairly simple piece of code.

[adam-lynch]

Yeah. Thanks.

Made a small change (8d39e6f) and published as 2.0.0.

[haydenbleasel]

Yep awesome - no point building the message if we're not logging it. Thanks mate.

Nothing is foolproof. I managed to break it in 3.0.0. Just added tests, fixed it and published now as 3.0.1.
