Browsers without script type module #611

So this is my new user experience: I've never heard of Transcrypt before today. I run the "hello" example on your front page. I click the "Click me repeatedly!" button and nothing happens. I open the inspector console and see an unhelpful "ReferenceError: hello is not defined" and the debugger provides no insight into the cause of the problem. I try using my alternate browser and get the same result. I read the whole of the https://www.transcrypt.org/documentation#faq and look through the contents of https://www.transcrypt.org/docs/html/index.html and still have no idea why your demo doesn't work.

My browser is Pale Moon. My alternate browser is Waterfox. I have not used Chrome or Firefox for over a year now and for various reasons I don't intend to go back to either of them. I did eventually try Edge, where it does work, but I never use Edge for anything other than testing and it took me a few hours to remember that it's even installed. Eventually I did figure out this must be because neither Pale Moon nor Waterfox support ES6 modules in client-side scripts, though I didn't even know this before today (i.e. nothing else I do on the Internet requires ES6 modules because it works just fine in these browsers); several Internet searches revealed little indication of this fact, and absolutely no indication that Transcrypt requires ES6 modules.

https://caniuse.com/#feat=es6-module shows that the first time ES6 modules were supported in any major browser was with Chrome 61 on September 5th, 2017. The feature is less than two years old. I'm surprised that any product would require such a feature without even mentioning it does so.

So, if I may make a few suggestions to aid others who may be in the same position as me, looking to use Python in the browser and believing Transcrypt to be the best way to do that. Even if nothing is done, at least those people will hopefully find this GitHub issue and understand the situation.

1. At bare minimum, please make it clear that Transcrypt requires ES6 modules in your hello-world example, in your FAQ, and in your documentation.
2. If possible, provide in your documentation alternate .html examples and necessary command line switches to produce code that doesn't require ES6 modules. If this is only possible in an older version of Transcrypt, it's still worth including this information, together with the last version number that supports it.

By the way, can anything be done about the elements on the Transcrypt website that lead to the home page and main sections when clicked? For some reason, they're not marked up as links; right-clicking doesn't give an option to open in new tab, and ctrl/shift is ignored when left clicking.
