checkscript() wrongly encodes non-ascii text

[e1fueg0]

When content takes more bytes than chars, the following command wrongly encodes text:

        content = tools.to_bytes(
            u"{%d+}%s%s" % (len(content), str(CRLF), content))

This code works correctly:

        content = tools.to_bytes(content)
        len1 = tools.to_bytes(u"{%d+}" % len(content))
        content = len1 + CRLF + content

And also pls propagate out server message in case of error.

Also pls expose the data from putscript().
And the code can be taken from putscript() to fix checkscript().

        content = tools.to_bytes(content)
        content = tools.to_bytes("{%d+}" % len(content)) + CRLF + content
