Fixed problem with default value of btdatastore.db.location not matching up with Linux install instructions
Fixed a build issue on Windows.
Cleaned-up/improved POMs.
Improvements to POM:
* Switched from exec:exec to exec:java.
* Got rid of copied dependencies in ./lib (commons-io.jar and js.jar) and used maven dependencies instead.
* Had the 'js' execution run on the package phase (it was being ignored because it wasn't bound to any phase).
Cleaned-up duplicate dependency in parent POM and modules (junit).
Fixed an issue with relative paths.
