2.0 - New design, new features

Most of the changes in 2.0 were made quite some time ago (about seven months) but were just now released.

• The interface looks much nicer now, thanks to Picnic CSS. 🎉
• Multiple file selection works far more frequently now, though it still depends on browser support, which is surprisingly bad on Android. ☹️
• If port 3000 is taken it will try 3001, and so on. You can still specify a port using the PORT environment variable.
• The IP address of the device on the local network is printed at startup. In terminals that support hyperlinks you can click to open the browser.
• Error pages. Yes, they didn't exist before. 😱
• Renamed! Previously the name was a super-meh "httptooth.js". Now it's changed to H Bridge. An H Bridge is an electronic component, but in this case it also stands for "HTTP bridge," because it, well, creates a bridge between devices, using HTTP.

That's all folks!™*

Avoid overwriting uploads

Improvement to avoid overwriting files: Appends a random number to the file name of uploaded files before saving. Changing the file name when not strictly necessary is sub-optimal and should be changed in a future release.
