New ArduinoJSON beta doesn't compile with ESP8266

[markbeee]

From version 6.0.0 (beta) Arduino JSON library doesn't compile with webthing-arduino/ ESP8266.

Quote from [https://github.com/bblanchon/ArduinoJson/issues/760]
"Indeed ArduinoJson 6 replaced the concept of JsonBuffer with the concept of JsonDocument.
To fix this error, you need either:
Downgrade ArduinoJson to 5.x (recommended as v6 is still in beta)
Upgrade your program to work with ArduinoJson 6"

According to the ArduinoJson website version 6 will be in beta for the rest of 2018 so I think the correct option is to require the use of version 5.

Please see if this can be tweaked in make files I just added.

Search tag: error: 'StaticJsonBuffer' was not declared in this scope

In my case this was the errormessage. I first searched for this error but then found this issue so i add this line in this issue for later people searching for the errormessage.

@hobinjk the work to upgrade from ArduinoJson 5 to 6 does not look huge: https://arduinojson.org/v6/doc/upgrade/. Would it make sense to upgrade?

Supporting both versions would be doable, but would it make sense?

Hi, it's already stable, so IMHO is a good time to update this library.. 😃

Thanks for all.

@markbeee @rzr @willdurand @novski
Sorry to mention you with @ 😅

@hobinjk is working on this in the pull request #95
.... and needs to be tested. 😬

Thanks and regards,
Matias,

If you update it please also try other sample apps built with top makefile
