Fix the way system files are handled at surf startup.

Browse source 
1. Do not chmod existing directories.
2. Fix the handling of tilde expansion in paths, don't expand ~foo to
   $HOME/foo but to foo's home directory.
3. Separate the creation of files and directories. We don't have to
   worry anymore about pathnames having to end with a '/' to be correctly
   handled.
