Support UMD

[kevinresol]

Support adding -D mui.global to switch to @:native generation so we can use UMD module without the build process

Thanks, I'll check my other branches to sync and I'll merge 👍

Just a regex find and replace in vscode:

@:jsRequire\('@material-ui/core', '(\w*)'\)

#if mui.global @:native('MaterialUI.$1') #else @:jsRequire('@material-ui/core', '$1') #end

That doesn't cover all cases, though. See line 25 of Table.hx for example.

Edit: also, mui.lab and mui.icon packages

I think there is no cdn-hosted umd-build for lab (or at least I can't find it)
