As long as the numeral is not the first character, it shouldn't force
quoting on the atom.  For example, abc123 does not need quotes.

Fix to compile on R13A

Since the lager_format rewrite, ~p and ~w now have different behaviour
with regard to printing lists as strings.

Conflicts:
	src/lager.erl

Stricter eliding of terms

Faster string formatting

If the result of the string format was longer than the remaining length,
the returned remaining length would be negative, which would make very
strange things happen.

Fix how the name/pid of the process is printed in crash reports

Before this fix, the code assumed that processes without a registered
name omitted the {registered_name, X} tuple in the crash report. In
actual fact, process_info/2 returns [] when the process has no
registered name, so unregistered processes were being printed with a
"name" of "[]". This corrects the code to print the Pid in this case
instead.

Specifically, the handling of lists/binaries/atoms is closer to
io_lib:format's behaviour, and some regular expressions are eliminated.

Use mfargs instead of name attribute as the way to detect supervisor_bridge

Fix issue #20

Make the tests less dependant on timer:sleep()

Fix typo in README

Several fixes for printing binaries, improve quote stripping

In string mode, "..", '..' and <<"..">> are stripped, just like with
io:format.

As Ryan pointed out, the 'name' of a supervisor's child may be
'undefined' for a simple_one_for_one supervisor.

Fix term printing in errors to properly show embedded lists
