added `==` for PJsonNode
adding header pragma for printf ffi example
Fixed #1172 (for real)
Properly terminate "nimrod i" on end of file.

Nimrod in interactive mode got stuck in an infinite loop when
encountering EOF (Ctrl-D), unless GNU Readline was being used. This
change mimics the GNU Readline behavior in rdstdin.nim and calls quit(0)
when encountering EOF while reading from stdin in interactive mode.
