docs(manual): update image references

[kwonoj]

Description:

It is not clearly known, but github seems prevent to render svg content in repo as markdown content, serves as plain text directly. (http://stackoverflow.com/a/21521184 / isaacs/github#316)
This PR updates image reference to use rawgit (https://rawgit.com/) serves correct content type.

Maybe just replace image to non-svg would be better solution? /cc @staltz

Oh, wait a minute. That SVG is primarily used for the ESDoc website, and works normally there. While it is possible to open the docs/ directory in GitHub and just read it from here, the recommended docs should be reactivex.io/rxjs. This is normal also in Cycle.js docs https://github.com/cyclejs/cyclejs.github.io/blob/master/_posts/2015-01-30-dialogue.md and also in React docs https://github.com/facebook/react/blob/master/docs/docs/thinking-in-react.md

And it's important that the image is SVG, for good and scalable resolution, but specially because the SVG file is text/code which can be edited. I.e. no one needs some "original" Illustrator file if they want to edit the image. It's open source.

This PR's not supposed to check in immediately, wanted to confirm its behavior. So it's ok to leave as-is? I thought it's expected to display some sort of images, (may other ppl could think same if they visit github only)

[staltz]

Let's make sure they see a link to http://reactivex.io/rxjs

[kwonoj]

OK, let me close this PR without merging, thanks for clarification and sorry for inconvenience. Totally my misunderstanding.
