Support https

Our svn repositories are located at a https address. I get the following error trying to connect:

The repository at https://svn.example.com/svn/repo could not be accessed. Error message from 'svn info':
svn: PROPFIND request failed on '/svn/repo'
svn: PROPFIND of '/svn/repo': SSL negotiation failed: SSL error: unknown protocol (https://svn. example.com)
