Enter single url to document

[daleharvey]

Its usually easier to just give the url to the doc than to seperate its db + docid

[neojski]

As far as I remember I did it because it's not always possible to know which part of the url is the docId. But it's probably only with _design/designDoc, right?

[daleharvey]

The above commit / big PR does it, it takes out the first /dbname/ then joins the rest of the url so the rest is the docId

Fixed in #8

Now I know why I did that:
suppose I have a corsproxy on 9292. Then http://localhost:9292/localhost:5984/xxx/yyy does not work.
