Wip/25 add gain node

[muuki88]

I added a minimal working solution for a gainNode. Tested on Google Chrome 56.0.2924.87 (64-bit) / Ubuntu 16.10. See #25

• Make gainNode configurable
• Provide a test
• Test on more browsers

Sorry, I created the PR from the wrong branch on my fork.

I added a gain option to the IStreamClientOptions. Testing with the demo/typescript-project wasn't possible as it depends an actual deployed version. How to you test this locally?

To test if typescript-project works fine, you can use npm pack (which creates .tgz) + npm install (local tgz)

Considering your pull request: i thought that it should be possible to tune gainNode value "in runtime", not only during initialization. To make "mute" function or something like that. Correct me if i wrong.

And thank you for your work.

Sounds like a good idea :) Will work on that ASAP

And thanks for the hint on how to test this locally. Wouldn't it be possible to reference it by going up the directory a few steps?

This is probably possible, but partially ignores node mechanism of modules resolve. You may be can also try this (https://docs.npmjs.com/cli/link)

Considering making it configurable, i think you can just add method like getGainNode to interface that will return existing gain node and that will allow users to manage it in any desired way. (probably we can also remove new 'gain' property from option).

What do you think about that?

Sounds good to me. Will change ASAP
