New fork

I needed to have this code working properly for me, so I forked it and made lots of changes to it.

The most important new features are:
- Works properly with recent versions of IE (and not at all with old ones about which I don't really care)
- Clock title
- Proper skins for digital clock and clock title
- Synchronize with web server clock
- Fixes in README.md

Have a look at it if you want.
