Fix ordering of SNAPSHOT and RELEASE versions

Update ProjectVersionsParser to correctly order versions by comparing
the version number before the qualifier. The following order is now
adhered to:

	4.0.1.BUILD-SNAPSHOT
	4.0.0.RELEASE
	4.0.0.M2

This commit also refactors the ProjectVersionsParser to improve
readability.
