ObjFW  Changes On Branch 98f171212dd4ecf9

Test if autorelease pool releases everything correctly when thread is ended

Make strings \0-safe

Cleanup OFXMLElement

Add finalization to OFXMLParser
Add namespaces to OFXMLParser
Add support for different encodings to OFXMLParser

OFTime

Tests for OFFile.
Tests for OFNumber.
Tests for readLine:.

Serialization

OFQueue
OFSortedArray

OFBase64
OFDirectory

... and of course enhance the already existing classes!
