Rewritten Exception class. Throw exception object, not its pointer and
catch by reference, so that remove problematic delete operator for
catched exception.

Added XML2SAXMetalinkProcessor class, which is a lot faster than
the predecessor, Xml2MetalinkParser class.
I tested them against 94KB metalink file with 1234 chunk
checksums.
The new one parsed it in 22msec, while it took 6000msec with old
one.
