Updated `libsite.sh': cleanup
Updated unit-testing/citm framework

Updated `module/unit':

    Added awareness for the new `dot' notation defining the output
    format of the given function (for example `.csv', or `.json') -
    there slipped under the radar and never got tested since this new
    naming standard was introduced into site.

    Perform set-up of the CI/UT host, which effectively means you should
    never run this on your own machine.

Updated `examples/site.conf.eg':

    Added examples that align with the unit-testing out-of-the-box.

    Removed the `.' tldid, as this is now handled in implicitly.

Update `unit/citm': verbosity

    New function called `run' which all commands should be wrapped
    with; this way it will print out what it is going to do, so makes
    trouble-shooting from the CI output easier.

Updated `.travis.yml': re-ordered and enabled all

    All primary modules have been enabled, and ordered as per
    dependency rather than anything else.
Overhauled `module/dns': rewritten from scratch
Updated dns unit tests
Updated `module/remote': cleanup

Removed the cfrun function which was out-of-place, and moved some
general ssh options to the top of the file.
Added remote unit testing
