Pull in latest Mermaid JS - 8.2.6

[simonwfarrow]

Hi,

I have pulled down the latest mermaid release from here
This has dropped the CSS files, so I have removed those.
I have also added a new parameter called mermaidTheme which allows you to set which theme to use as per this breaking change

Are there any reasons not to merge this pull request?

@aazon this solution is not best practice in my opinion, because it does not exactly solve the problem (see #361 #362).

See #443 for later upgrade.

But why should this implementation be better than the CDN method?
You're must download mermaid from CDN to use it - so even your version is from the mermaid CDN.

In 2-3 Weeks your version is outdated and has to be updated manually via a new PR.

BTW, Git is not made for handling framework's (each upgrade, your repo is growing by some Megabytes) - That is why node was invented (besides many other reasons).

Thank you for the submission, and apologies for not looking at it sooner. This change is now superseded by #443
