Stop printing newline on stderr when outputting to stdout

[hairyhenderson]

Fixes #1075 and #1074 by removing the feature entirely.

Note that this will change the perceived output when gomplate is used interactively with a template that does not end in a newline. For example:

in bash:

$ gomplate -i "hello world"
hello world$ 

in zsh:

$ gomplate -i "hello world"
hello world%
$ 

Note that this does not affect the stdout stream, which was never modified. Only the stderr stream was modified (and is now no longer modified).
