logtail: tail -f logfiles in the browser with websockets

NB: incomplete hack!

How to build and run

$ rebar get-deps
$ ./start-dev.sh

Now visit http://localhost:9090/index.html

(still need to make cowboy treat / as /index.html)

Configuration

Add entries to the sources section in app.config:

Single file

{file, "/path/to/file.log", []}

Multiple files, wildcard expansion

{files, "/var/log/*", []}
