Fix typedoc URL generation (for /docs)

[robiiinos]

This PR replace #180

According to the https://github.com/TypeStrong/typedoc#theming documentation, we're able to specify the branch to stick with when generating docs. According to the current README.md, I specified the master branch.

I also re-build the docs to fix all of this.
Thanks @s1na for helping me out !

PS : We should be able to keep the docs generated as it is until you change the *.ts file

That was fast!

Ah, this PR seems to also fix an issue with union types, I imagine because you have a newer version of typedoc installed and they've fixed this.

This already looks good to me. I think having the docs point to master instead of a specifi commit is more flexible and less likely to break. And in the worst case, if the docs are out-dated, they would point to a wrong line. I think it's a good trade-off. @holgerd77 what do you think?

@s1na Yes, I think so too, thanks @robiiinos for the PR! 😄

Side note: I think doc generation process has settled enough, we should also take on ethereumjs/ethereumjs-config#11 short-term. This PR is again a perfect example why this matters (even if we just have ONE single build command in it). Such a change would otherwise have to be re-distributed throughout all the libraries.
