Changes for version 1.01
- use :raw:perlio to open files for retarted operating systems, although :perlio *should* work - maybe a perl 5.8 issue? (reported by sten).
- Urlader::lock now official part of the API, and doesn't cause "free unreferenced scalar" error.
- urlader-util - generate new urladers, maybe other stuff
- Urlader - installer-less single-file independent executables
