class Textile not loading; use \Netcarver\Textile\Parser instead

[jsoo]

I don't know enough about the autoloader to know why class Textile isn't loading, but it isn't. The template "worked" because plugin_verify() does the Textile parsing on install. (And now I see I could have used \Textpattern\Textile\Parser instead of \Netcarver\Textile\Parser, but no diff in this case.)
