(CFACT-145) Fix segfault when libruby is not found.

When setting up whether or not stack traces should be printed with
exception messages, we set the option on the ruby object outside of
where it is being checked for null.

The fix is simply to move the line up inside the block where ruby is
valid.

(maint) Remove openssl version from README.

Removing the openssl version requirement from the README.  We have no
hard requirement on openssl version; the version presented here was
mostly a suggestion.  Removing it to avoid confusion.

(CFACT-165) Build cfacter for lucid and squeeze
(maint) Define a minimum of 1 job to run

Prior to this commit, on some systems, `nproc` wasn't available on the
system. Since we use this to define the job threading for building with
cmake, having nproc not be defined left us calling `make -j`. This
basically tells make to build with an unlimited number of jobs, eating
up all available system memory, making the build fail with `virtual
memory exhausted: Cannot allocate memory`. This commit changes how we
are defining the number of jobs to thread at once. We want to use
`nproc` when we can, but when we cannot, we just set it at `1`. Ideally
we build with `nproc+1`, so this ensures that we are not eating up all
available memory, and are running jobs at maximum efficiency when
possible.
(maint) Update buildtime requirements

CFacter has a soft requirement on openssl >= 1.0.1g, but it will still
build with other versions of openssl. Since we want to enable as much
functionality in our builds, we want to link against openssl if
possible. Older versions of debian/ubuntu only have openssl in the 0.9.8
range, so when it comes to runtime dependencies, we want to allow the
user to install whatever libssl is available on the system. In this
case, we have a choice between libssl1.0.0 (for openssl1.0.1) or
libssl0.9.8.

Also, it was a little silly that we were using libcurl4-gnutils, rather
than libcurl4-openssl. I believe the original choice was rather
arbitrary, but since we're using openssl here anyway, it makes sence to
use that version of libcurl.

(CFACT-137) Define UNICODE on Windows

Force use of Unicode APIs on Windows by defining UNICODE and _UNICODE,
following the recommendation of utf8everywhere.org, and convert to and
from UTF16 for the API calls as needed.
(CFACT-137) Add Boost.Nowide for Windows UTF-8

Add the Boost.Nowide (candidate) library for UTF-8 aware standard library
wrappers on Windows.
Replace our own to_utf8/to_utf16 and environment manipulators with
Boost.Nowide. Also use it for fstream/fopen. cout/cerr aren't replaced due
to the dependency on building a binary object, to be resolved later.
(CFACT-137) Use Boost.Nowide cout/cerr adapters

Use the Boost.Nowide cout/cerr adapters that ensure UTF-8 will be printed
correctly on Windows. Requires building the Boost.Nowide library on
Windows, and adds tests for the library.
