Also removed commented out code.

There are still differences between the erlang io_lib and the trunc_io in
how ~p/~P are handled, but a first step is useful here.

Handle uncaught throw error messages better

Add Travis CI hook and build status

Better error handling for 'special processes'

binaries with escaped chars are not formatted correctly by ~p

Add support for badrecord errors

R15 support

Whenever we have the filename we ALWAYS have the module name, which is
effectively just as useful and already printed.

Tests now pass on both R15B and R14B03.

Thanks for Kostis for helping me figure this one out

Fix specs so that they correspond to the code

This is just silly busy-work since they're library applications, but
whatever.

Add compiler and syntax_tools as dependencies

Fix atom leak

Support for printing bitstrings (reported by @freeaakk)

Additional changes and formatting by Andrew Thompson

Bitstrings are binaries that don't end on an 8 bit boundary, so dealing
with the trailing bits is annoying. Thanks to the bit_size bif we don't
have to resort to io_lib for printing them.

Better crash reports for processes started via proc_lib, Fixes #31

don't quote atoms just for containing numerals

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.
