Update tutorial.md
Data.CompactString is no longer needed in ghci. `runIOE` has been deprecated. Everything now works without runIOE.

### Connecting
|
||||
|
||||
Establish a connection to your local Mongo server on the standard port (27017):
|
||||
|
||||
> pipe <- runIOE $ connect $ host "127.0.0.1"
|
||||
> pipe <- connect $ host "127.0.0.1"
|
||||
|
||||
A host with non-standard port would look like `Host "127.0.0.1" (PortNumber 27001)`.
