Reliable formatting of ${ooo.user} variable in Open Office Startup

- Open office seems to be temperamental about starting if its env:UserInstallation argument doesn't begin "file:///" on Windows or "file://" on Unix. The argument may not contain any backslashes either. Unfortunately, this doesn't correspond to Java's File to URI conversion
- Created OpenOfficeURI class for doing the formatting instead instead
