Added rollup config version

[chimon2000]

This version reduces the file size further to 74kb minified (24 gzipped).

@kartsims all requested changes added!!!

Yeah!

I tested it, removed a few more webpack dependencies, and got the following output :

~/dev/vue-customelement-bundler ■ npm run dev

> vue-customelement-bundler@1.0.0 dev /Users/simon/dev/vue-customelement-bundler
> rollup -c -w

Any idea where these warnings come from ? I am merging the PR anyway (to a rollup branch) but that would be less scary without those warnings ;)

What I did :

• Update the post (should be online in a few minutes)
• Created the rollup branch based on yours, minus a few remaining webpack dependencies
• Added reference to the branch in the master's README.md

The final gzipped file is 25% lighter, that is something ! Thanks again :)
