Update graph coloring example with placeholders
This replaces the former graph coloring example with a new formulation
that makes use of the newly supported placeholders.

Support placeholders with #external declarations
This adds support for declaring predicates as placeholders through the
“#external” directive in the input language of clingo.

Placeholders are not subject to completion. This prevents predicates
that represent instance-specific facts from being assumed as universally
false by default negation when translating an encoding.

This stretches clingo’s usual syntax a bit to make the implementation
lightweight. In order to declare a predicate with a specific arity as a
placeholder, the following statement needs to be added to the program:

    #external <predicate name>(<arity>).

Multiple unit tests cover cases where placeholders are used or not as
well as a more complex graph coloring example.

Update change log with dependency change
This adds the dependency change from Boost (for program options) to
cxxopts to the change log.

Format change log sections with proper headings
This makes the change log sections have proper headings, which were just
normal text before.

Update cxxopts to 2.0.0+3+gabe9ebd
With cxxopts 2.0.0, positional arguments weren’t recognized when other
command-line options were passed before. This has been fixed in the
meantime, but there is no release with the bug fix yet.

This updates cxxopts to a newer commit to ship anthem with this fix.

Drop Boost dependency
Boost was only used for program option parsing. To avoid this huge
dependency, this commit replaces boost::program_options with cxxopts,
a header-only library with the same functionality.

cxxopts is added as a submodule, and Boost is removed from the
dependencies in the code and Travis configuration.

Install g++ package explicitly on Ubuntu
Apparently, g++ is only installed because of the Boost dependency.
Make the g++ dependency explicit to avoid future package errors.

Switch to C++17
With C++17, optionals, an experimental language feature, were moved to
the “std” namespace. This makes C++17 mandatory and drops the now
obsolete “experimental” namespace.

Switch Travis to Docker
As Travis only provides outdated packages (compilers in particular),
this changes the Travis configuration to use Docker images to build and
test the code. This also has the benefit that multiple distributions can
be tested and not just Ubuntu.

For the time being, Arch Linux and Ubuntu 18.04 are added as supported
platforms.
