- Update for Qt 4.8.5 and Qt 5.2.1
- Use configure.bat explicitly as the configure command...

Furthermore, simply be aware: building from source *requires* a .gitignore
file to be added to the extracted tarball, and perl has to be in the PATH.
(I'm trying it with the perl from my msys git install, and all the other
tools in the PATH implied by that...)
- Remove "-nomake demos" -- it's not there anymore
- Version differences: bin dir and moc output differ from Qt 4.x to 5.x
