Remove babel-preset-vue as it is not being used

Resolves #836.

Ah I finally found the part of the Vue docs that made this make sense: Vue JSX is an optional extra that many people using Vue won't need. (And confusingly the Vue docs only refer to babel-plugin-transform-vue-jsx and not babel-preset-vue, even though the babel-plugin-transform-vue-jsx install steps pretty much just duplicate babel-preset-vue?!)

I think babel-preset-vue is supposed to be a preset for all vue plugins:

https://github.com/vuejs/babel-preset-vue/blob/b31b78f47f4ac39ce4d83aaa7c22b169d9e6010c/package.json#L33-L38

https://github.com/vuejs/babel-preset-vue/blob/b31b78f47f4ac39ce4d83aaa7c22b169d9e6010c/index.js

where babel-plugin-transform-vue-jsx is one of the included plugins.

Yeah but the usage instructions for babel-plugin-transform-vue-jsx are pretty much "install all the packages manually". But yet they have a parent package that includes all the other packages, the docs just don't mention it.

I see what you mean. Yeah, that's odd :)
