GGUI crashes when certain keys are pressed (The Windows key, for example).

Relevant code:

https://github.com/taichi-dev/taichi/blob/master/taichi/ui/common/input_handler.h
https://github.com/taichi-dev/taichi/blob/master/taichi/ui/utils/utils.h

It would be great to support all of these keys, or at least add a try-catch to avoid the window from crashing.

I have been asked several times whether the value filled in cc.spec.common.es.externalElasticsearchUrl requires an http prefix, but it is actually not needed, but this key is a bit confusing. I don’t know if I need an http prefix sometimes when I look at it, so I think it’s clearer to change it to externalElasticsearchUrl to externalElasticsearchHost
