Version 2.0.2 - bugix release

Fix compilation issues for some examples

Fixed a compilation issue

Added #include <string.h>, because we use some of its functions.

Improved usability

The user doesn't need to change the library source itself to use some network/interface any more. She used to need to change Pubnub.h. But, in version 2.0.0, she just needs to #include the header for the network and #define Pubnub_BASE_CLIENT to the class to use, before #include <PubNub.h>

Fix example for AdaFruit Feather M0 WINC1500

Fix example for AdaFruit Feather M0 WINC1500 - it had bad JSON format for the message it publishes

Changes for Arduino Library Manager

It seems that Arduino Library Manager doesn't like the v prefix in name of the version, while Github likes it. Hopefully, it will now pick-up new releases of the Pubnub Arduino Library.

Fix timetoken issues on unstable (i.e. WiFi) networks

On WiFi and other unstable networks, timetoken reception could fail, thus subscribe would not work correctly (would not receive messages).

Arduino library specification support

Cleaned up WiFi101 shield and compatibles support.

Added library.properties to enable smoother integration to Arduino IDE.

Support `auth` parameter for PAM

Pubnub Arduino library now supports the auth parameter for PAM.
