Fixed outstanding bug with Vireo where relative paths for different
things were not in the places you'd expect.
+ Relative paths are now all relative to the Vireo Application base
directory instead of the Play Frameworks' current working directory
(where vireo was launched from).
+ Fixed tests that create temporary files so that they are not created
in the CWD of the play framework.
+ Tested by running Vireo from an directory with no write privileges.
bumped revision to 2.0.8.1 - bugfix release
