The online analyze tool does not show parse errors

[jbergens]

I tried to upload a stats.json file to the online analyze tool but it didn't work. In the browser console I can see some parse errors without details but the gui does not show any information at all. Since the stats.json is created by webpack it is hard for me to know what the analyzer has a problem with. me to know what the analyzer has a problem with.

It would also help if the analyzer page had some help information about how to create a stats.json etc.
