* Refactor code to be more robust. Run main logic inside a try {} catch {}
block. If there is any error, bail out and log all the command output
automatically.
* Rely on error code generated by chocolatey instead of scraping text
output to determine success/failure.
* Add support for unattended installs: (`-y` flag is a requirement by
chocolatey)
* Before (un)installing, check existence of files.
* Use functions to abstract logic
* The great rewrite of 0.9.9, the `choco` interface has changed, check
if chocolatey is installed and an older version. If so upgrade to
latest.
* Allow upgrading packages that are already installed
* Use verbose logging for chocolate actions
* Adding functionality to specify a source for a chocolatey repository.

* Removing pre-determined sources and adding specified source url in
it's place. (@smadam813)
