155645307a use partial strings for passing argv to toplevel.pl 
In run_top_level: rename variables, make them partial strings

The rename is mostly cosmetic: all of argv is passed, and if argv
contains flags, goals, etc, it's more than filenames.

Using partial strings instead of atom came from discussions about how to
pass goals in the CLI, and can thus be considered preliminary work for
that.

In toplevel.pl: convert partial string to atom before passing it to
`use_module`.

8b1df2e9ca ADDED: CLP(ℤ), Constraint Logic Programming over Integers 
library(clpz) implements declarative integer arithmetic.

The most important predicates for reasoning about integers are:

    (#=)/2    equality
    (#\=)/2   disequality
    (#<)/2    less than
    (#>)/2    greater than
    (#=<)/2   less than or equal to
    (#>=)/2   greater than or equal to

In addition, the library provides several global constraints, such as
all_distinct/1 and global_cardinality/2, and reification predicates
that reflect the truth values of constraints into integer variables.

Enumeration predicates such label/1 and labeling/2 can be used to
search for solutions over finite domains.

Almost all Prolog programs also reason about integers. Therefore, I
recommend to add this library to your .scryerrc configuration file so
that declarative integer arithmetic is available in all your programs.

Enjoy!

45d4f46024 main: skip args[0] 
This is a bit pedantic, it's unlikely that the executable would be
called `-v` or `--version`. However, it seems slightly more correct to
disregard argv[0] when checking flags.

896f2aeb74 main: add -v/--version flag 
Added a new dependency to take care of pulling in the version from git
at build time.

Args handling is minimalistic, but there wasn't any before, so I figured
this might do for now. (Eventually, some proper `--help` and usage
output might come in handy?)
