baseUri isn't honored by server

[shesmer]

I am trying to create a WebDAV based server that doesn't listen on the root and therefore I need a baseUri when setting up the server.
In doing so I noticed that the baseUri gets overwritten afterwards through this line in server.js
this.setBaseUri(this.guessBaseUri());
This will always set the baseUri to /

I was able to fix this by adding this line
if (!options.baseUri)
this.setBaseUri(this.guessBaseUri());

This causes the baseUri guessing only to happen when there wan't an explicit one set.

This of course is just a suggestion. :)

Can this please be fixed ?
