Patch from Edmanm, slightly modified.  Original change list:
   - Support running the Tor service with a torrc not in the
     same directory as tor.exe (Bug #356) and default to using the torrc
     located in the %appdata%\Tor\ of the user who installed the service
   - Removed the supposedly misleading error message mentioned in Bug #294
   - Fixed some CloseHandle()s that should've been CloseServiceHandle()s
   - Fixed some nt_service_foo() return values to be consistent
   - Resolved some nt_service_foo() DOCDOCs
   - Fixed one trivial typo that I happened to randomly notice
 
 Changes:
   - Make more comments into "imperative" house style.
   - Remove special handling for "-f"; only use --options.
   - Quote all options.
   - Clean up whitespace
