Re-work filetransfer/bytestream stanza toXML() method to use
XmlStringBuilder. Move the ELEMENT and NAMESPACE definitions in the
right place, ie. the stanza class.
No code changes. Proofread API docs for Presence.java
Fixed grammar / unclear sentences in some javadocs.
Changed some nouns to be more consistent with API terminology.
Fixed some typos.
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.
