GET requests to socket.io with absolute path

[joluxer]

Padwiki is not working, when etherpad is behind a reverse proxy in a subdirectory URL.

The client code is making GET requests with absolute paths starting from /. Tried to fix this in wiki.html, but still are some calls to /socket.io/... left with absolute path, which I cannot find.

Otherwise great work!
