Go's text/template package with newline elision

This is a fork of Go 1.4's text/template package with one addition: a backslash immediately after a closing delimiter will delete all subsequent newlines until a non-newline.

eg.

{{if true}}\
hello
{{end}}\

Will result in:

hello\n

Rather than:

\n
hello\n
\n
