Generating configs on Windows has some broken folders due to forward slashes

[ghost]

It seems like using os.getcwd() on windows causes the config to look like this:

# Directories to load user modules from
# e.g. /path/to/my/modules
extra = [ 'c:\Users\Bekey\Desktop\buffy/modules/' ]

which then causes issues because it tries to escape the first character of every folder.

Yeah, all of this should be replaced by the os path separator, simply fix to make this system agnostic
