Updated the dependencies so that it builds properly on Windows,
additionally, fixed the registered command for starting it as
a service (needed to add the config file option). This currently
standardizes it as a C:\telegraf\telegraf.conf on Windows.
Incorporated the library github.com/kardianos/service to manage the
service on the various platforms (including Windows). This required an
alternate main function.
The original main function was renamed to reloadLoop (as that is what
the main loop in it does) (it also got a couple of parameters). The
service management library calls it as the main body of the program.
Updated the windows dependencies so that the versions matched the
dependencies for Mac OS and Linux. Additionally added some that were
complained about being missing at compile time.
This constitutes a large change in how we will parse different data
formats going forward (for the plugins that support it)
This is working off @henrypfhu's changes.
