replacing all {filePath} instances and adding {filePathDecoded}

I used grunt-include-source to create a list of hyperlinks to html files. I made 2 changes to suit my case.

1. Replaced all instances of the {filePath} token instead of just the first (although I don't need it any more, I think I might soon.)

2. Added a new token for {filePathDecoded} to write the decodeURI version of the path.

The intent is to produce a template: &lt;a href="{filePath}"&gt;{filePathDecoded}&lt;/a&gt;
