beta 1

• added windows service support - now can self install and run as windows service
• to install as windows service:

winevt-tailer -i
or
winevt-tailer -i <CLI args>

• functionally this service will be equivalent to CLI: winevt-tailer <CLI args>
• to change args - just call the same "-i" command again with different set of CLI args.
• service logs go to c:/ProgramData/logs :

    windows_tail1.log          -- Windows events in one-line-JSON format, ready to be streamed by Mazmo Agent 
    winevt-tailer_tail1.log    -- service instance log

where 'tail1' - default logical tailer instance name, controlled by "-n" cli arg

• to uninstall:
  winevt-tailer -u
