If the files passed to the '-t' option are all '.js' files (or
the 'run all tests' option is used) and the '-i' option is not
passed, all tests will be search for the string
'require local modules: '.  Only the first instance of this string
will be used.  Following the colon should be a list of either local
modules (i.e. files in the '../include/' folder relative to the
test runner's directory, without the '.js' extension) or paths
to other Javascript files.  The list of modules and/or files should
be comma-separated.  These files will then be included in the generated
HTML file for the appropriate tests as if the '-i' option had been used.
