Beginning of Folder Manager Component. 

build.sbt:
- Added dependency for RxJava library. Usage is described below.

refresh-eclispse.sh
- New Script to refresh Eclipse dependencies from SBT managed
dependencies. Used when SBT dependencies change and we want to pull them
into Eclipse workspace.

Added a new class ImportFileWatcher:
- Wraps a Java WatchService to monitor a configurable part of the
filesystem for new JUnit test report XML files. When files are detected
an import is attempted.
- Provides an RxObservable to emit custom events. The intention is that
the low level file system events are encapsultated by this component and
merged with custom events to provide a consumable stream of the
ImportFileWatcher's activity. As the Folder Manager component develops,
it might have other sub-components (db access and file upload) that
would also provide event streams. File Manager could aggregate these
streams for consumption by an external component.

Added Event Class Hierarchy to model different events:
- FileSystemEvent (A)
    - ImportEvent (A)
        - ImportStarted
        - ImportSuccesssful
        - ImportFailed
- ImportEvents provides convenience factory methods for the above
events.
- Other File Manager Activities should subclass FileSystemEvent to model
any events emitted (eg. File Uploaded, Folder Deleted).

IBatchImporter / BatchJdbcImporter / TestDataGenerator:
- Extracted IBatchImporter from BatchJdbcImporter and removed static
modifiers from its public methods. This makes it easier to work with in
tests. Planning to put it into server environment with some kind of DI
mechanism.

ImportFilewatcherTest:
- New test to cover main ImportFileWatcher functionality. Will need to
be extetended as we move forward.

ReportParserBulkTest / ReportParserTest:
- Updated to use Path objects. Plays nicer with newer stuff like
ImportFileWatcher.

test.properties / TestProperties
- Added a property to set the File Watch root folder. Used in
ImportFilewatcherTest.

malformed-input-file.txt / TestDataInfo:
- Added file with bad data and path to this file for use in
ImportFilewatcherTest.

logback-test.xml:
- Added to configure logging in test.
