add support for a general suffix instead of a single extension

now suffixes like Spec.js and .test.js also work
also removed the verbosity print call which was spamming the console

An example conf with this setup:

    "JavaScript": [
             [ [".js"], ["public/js"] ],
             [ ["Spec.js", ".test.js"], ["../test"] ]
           ],
add test description for general suffix
add normalized extensions

i.e. in addition to extension provided in the conf it now also looks
for files with a period prefix either added or removed

this fixes the matching, for example, for '.cpp' and 'hpp' where one has
a leading period and the other doesn't
Fix a typo in the test description
