* Bug Fix: Empty .Site.Params.contentDir
When .Site.Params.contentDir is left as the default: "content", calling .Site.Params.contentDir returns nothing, or maybe an empty string. To fix this, we set a default value for .Site.Params.contentDir to "content" and the url is built correctly.
* Use the `default` function instead of `or`

Seems to be a Windows related thing. `.File.Path` returns a path with backslashes this adds a replace to make those forward slashes. This appears to fix#115
