Minor: typo in the web.mime documentation (i.e. in README)

[dumblob]

The list of routines in the README mentions 2x the same routine instead of the second routine being updateDb(source: io::Stream) => int.

Btw in all these documentation the term Functions is used, but Dao uses Routines (also internally) to distinguish pure functions (i.e. without side effects) from just a bounded reusable ordered code with input arguments and a return value. We should probably rewrite all mentions of a function to routine.

@Night-walker, do you actually still have commit access to this repository (either directly or somewhere else - where?)? @daokoder, I'd like to submit pull requests for these minor things - where should I submit them?

With regards to contributing, I can remember @daokoder argumenting GitHub is problematic in China. I'm following the https://notabug.org/ initiative already for about a year and it seems a good international and very independent platform for projects like Dao (NotABug can also easily be synced to read-only GitHub repos to gain popularity and allow GitHubbers to post issues).

So in case there is no good option currently in use, I would advocate for trying NotABug (of course first testing it's availability from China - according to web testers it should be available).
