single line support added

[alexm622]

fix #5
changes:

• added a license comment delimiter that works for both single and multiline comment formats
• added support for single line comment languages through the use of the
  constant SINGLE_LINE_COMMENTS in place of the postfix and uses the prefix as the comment
• added .gitignore to remove any binaries and temporary testing files from the git path
• added comments to utils/comments.go describing what type of file each of the lines corresponds to
• updated SupportedFileExtensions in utils/constants.go to better follow the standards of "supported file extensions", but i can't seem to find a place where this is implemented

current issues

issue	proposed solution
Makefiles still do not work due to the program matching based off of extension and Makefiles not having an extension	a fix for this would be to rewrite the matching method to include full filenames, this would also have the side effect of being able to specify specific files in the config, which would then require a little more rewriting on matching the config file to the comment prefix/postfix in comments.go

this will fail tests because of the new format of the license comments, meaning they'll have to be manually examined for this push and then the tests will have to be fixed as well
on another note this appears to have somehow fixed the issue with debug output

[alexm622]

the last push removed unnecessary debug

@Marvin9 the tests are not publicly included within the repository
that causes these new changes to fail the tests, a public inclusion of the tests would be beneficial, as the format of the licensing has been altered slightly to allow addition and removal of licenses in single line only languages
