added hass_is_global config parameter

[craigbarratt]

This PR adds a config parameter hass_is_global (default False), which if set provides hass as a global variable in all pyscript contexts.

@raman325 and @dlashua - I invited you to the forked repository. Please review and feel free to push any changes to craigbarratt/pyscript-hass-is-global, or just comment here.

This will resolve #46.

[raman325]

I just pushed the change I had suggested here: #42 (comment)

[craigbarratt]

Thanks! Should that also be done in __init__.py (it's aways used cv.boolean)?

[raman325]

no cv.boolean can be used there because the backend is aware of the custom config validators that HA provides. The issue is that the serializer that delivers the schema to the frontend (for config and option flows) was not aware of the custom validator before I submitted that PR, so it doesn't know what to do and throws an error instead of showing a form.

[craigbarratt]

Ok, thanks for the explanation.

[dlashua]

I've loaded this branch and it seems to work fine with no issues. I haven't found anything interesting to do with hass just yet, but the things I expect to be there are there and are usable.

[craigbarratt]

Thanks for the feedback and fixes. I just released 0.32 (which has the HASS restart fix, config improvements from @raman325 and @state_trigger support for multiple arguments, lists and plain state variables to mean any). I'm going to merge this and we have time to test and tweak if necessary.

[dlashua]

excellent, I'll pull master now so it gets a good test run.
