instead of using the old baseName=smack appendix=project.name approach,
we are now going convention over configuration and renaming the
subprojects directories to the proper name.
Having a prefix is actually very helpful, because the resulting
libraries will be named like the subproject. And a core-4.0.0-rc1.jar is
not as explicit about what it actually *is* as a
smack-core-4.0.0-rc1.jar.
SMACK-265
Use Type enum instead of String for PrivacyItem's constructor. Add
getName() to PrivacyList. Remove PrivacyRule, as it just adds unnecessary
complexity spliting PrivacyItem and PrivacyRule, they belong
together. Don't mix camel-case and c-style method names. Some minor
improvements. Add parser test.
