Allow test searching to be limited by source folder

[GoogleCodeExporter]

Many projects have tests organised into source folders by type (eg
test-unit for unit tests, test-acceptance for acceptance tests etc).

It would be useful to be able to limit junitflux to a configurable set of
source folders (eg only src and test-unit), perhaps via a .junitflux config
file in the root of the project. JUnitTestFinder.getSourceLocations() could
then be limited to the defined set.

PS Great plugin!
