(maint) Set Release as the default build type.

Without setting the default build type, toolset defaults are used during
the build.  This change makes it so that running cmake without
specifying a CMAKE_BUILD_TYPE variable will default the build to
"Release".
(maint) Correct uptime hour format string

(maint) Move version information to the facter library.

Moving version.h to facter library so that it reflects the facter implementation version.
cfacter now calls into the facter library to determine the version rather than having the versionc compiled into two different executables.
Adding version to facter library name.
(maint) Fix where cfacter gets installed to.

Now that we don't build cfacter's dependencies, change back to installing cfacter to /usr/local/[bin|lib] by default.
