The generateBundle hook should be used instead of the onwrite hook.

So busy Recently, sorry for that. I had confirmed that this deprecated warning message appears after upgrade to rollup-1.0.0+. I'm working on it ASAP now.

[rj-hwang]

Main code change :

1. follow RFC: Standardise options and CLI flags #1479
   and Unifying Rollup options , since rollup-0.48.0, bundle.write(options) options.dest > option.file, entry > input. See 5519c45.
2. follow rollup-1.0.0: deprecations #2409, use generateBundle instead onwrite. See 589dc4b.

Release 1.0.0 to fix this issue.

Please check it.
