bug fix circular reference

Merge pull request #16 from bchr02/dev

Changes:
* new --silent option to turn off verbose logging
* only options with a default value defined within NodePreGypGithub.prototype.createRelease are passed to the first parameter of github.releases.createRelease(). When I introduced the silent flag I didn't feel it made sense that this property should automatically make it's way to github.releases.createRelease function. This prevents that.
* 100% test coverage, including a backwards compatibility section.
* running tests no longer includes the verbose messages that get generate from within the module
* coveralls badge now on README.md
* package.json's scripts.coverage now includes a command to post to coveralls when the COVERALLS_SERVICE_NAME and COVERALLS_REPO_TOKEN environment variables are defined properly.
* coveralls added as a devDependencies within package.json

Merge pull request #15 from bchr02/add-tests

**Changes:**
* adds test\test.js with over 97% line coverage.
* added a test and coverage section to package.json's scripts property.
* added some dev dependencies to package.json which are needed for testing and code coverage.
* removed some unneeded dependencies from package.json
* removed some unneeded modules that were required in index.js
* ```NodePreGypGithub.prototype.github = new GitHubApi(..)``` now happens immediatelly instead of within ```NodePreGypGithub.prototype.init()```. The main reason for this was so I could provide a  replacement mock to use within unit tests.
* added some missing escape characters, so ```/{version}/g``` is now ```/\{version\}/g```
