• Minor fix for the Makefile.
• Fixed CSS sourcemap.

Second development release

Major changes include:

• Chromium browser compatibility.
• Breakpoints are redrawn after file refresh.
• Multiple browsers are able to join a debugging session at any point.
  Previously, it was only possible before the session started.
• Error messages are displayed in the UI.
• UI files are embedded in the footle server binary. This means, we
  need only one file to use footle.
