fails build: <reportSet>'s <path> on Windows generates invalid report output filename

[jeffjensen]

Using 0.14.0, this config on Windows:

<file>
  <path>${project.build.directory}/${project.artifactId}-${project.version}.${project.packaging}</path>
</file>

Results in this output file path and name which is in error with the drive letters and pathing:

D:\(path)\target\site\(group)_(artifact)_(oldVersion)D:\(path)\target\(artifact)-(newVersion).(packaging)_output.html

Fixed with #236.
