Support Export Statements - WIP

[Cmdv]

this is linked to #71

Again I'm a little unsure about everything this currently covers as from the specs there are all these too:

export { variable1 as name1, variable2 as name2, …, nameN };
export let name1, name2, …, nameN; // also var, const
export let name1 = …, name2 = …, …, nameN; // also var, const
export class ClassName {...}
export default expression;
export default function name1(…) { … } // also class, function*
export { name1 as default, … };

export * from …;
export { name1, name2, …, nameN } from …;
export { import1 as name1, import2 as name2, …, nameN } from …;
export { default } from …;

So I'm missing things like from + * etc.

Incomplete support is better than no support, as long as it passes all existing and new tests.

I'll need to look into this a lot more as in all honesty I took what was in the original PR and just ported the parts I needed to these individual PRs.

I'll have a better look see if I can get as much implemented as I can. I understand you might not have the time to help so if anything at least I might have done some of the work towards implementing these and someone else can pick up 😄

Think I'm just doing a lot of guess work right now, not sure what needs to be done here

This is why we have minify tests, which minifys something and then tried to parse it. As long as that works correctly for all cases that can be pasrsed it should be fine.

feel free to close this as it looks like it was acheived in #80
