SurakWare Base Library 0.4.0

The purpose of the SurakWare Base Library (SWL/libswl) is to serve as a platform independent development framework for C++ and QPascal.
The SWL includes both thin layers over functionality exposed by the Linux and Windows operating systems as well as higher level classes for many purposes. Save for a few exceptions, the SWL is completely indpedenent from the STL and the C/C++ runtime library.
Platform independence has been achieved by encapsulating OS-specific implementation details in a number of SWL classes. There should never be a need to use "#ifdef"s to distinguish between platforms.
Enhancements:
- Some memory and file descriptor leaks were fixed.
- Some buffer indexing problems were fixed. I/O dispatcher problems on high load notifies were fixed.
- TFile::directory() was fixed.
- TEventManagers add/remove operation logic was improved.
- TNullEnumerator::moveNext() was fixed so that it returns false rather than throwing an exception.
- Some 64-bit vs. 32-bit compilation fixes were made.
- TStream::readTimeout and writeTimeout were backported from trunk to 0.4 (and thus introduced EIOTimeout exception).
- General improvements were made to TArgumentEvaluator and TAnsiColor.
- General code cleanup was done.
