v1.3.0: Homie topics more configurable and stability improvements

This is kind of a big one. Thanks to everyone involved.

New features

• You can now set the base topic used on MQTT if you don't want the default devices/ base topic (#44)
• You can also set the device ID to be used on the MQTT topic if you don't want the default hardware ID (#45)
• Breaking change (not in the API so still 1.x.x): The new OTA version string sent to the server is now of the following format: device-id=firmware-name=current-device-version=version-advertised-by-$ota (eg. da828fe0=sub2-relay=1.0.0=1.1.0). This makes it easier to parse server-side (#50)

Fixes

• A lot of work has been done to improve the stability of the MQTT connection when using SSL. Huge thanks to @jpmens which has been very active at testing, he helped a lot 👍 (#46)

Note: This required a lot of changes in the code, the most notable being most of the dynamic allocations were removed. In other words, there are now hard limits for things like the firmware name (see Limits.hpp and customize it if you need to).

• SSL/TLS fingerprint verification now works for MQTT (#42)

Note: The way the verification is done is not very secure due to some limitations of PubSubClient. Consider it as more secure than no fingerprint at all, but not bulletproof.

Docs

• The documentation was moved from the Wiki to the repo. So now, whenever you download a copy of the library, you have an up-to-date documentation for your current Homie library version

Web UI

• Polyfills are now included in the Web UI, so more web browsers are compatible (#48)
• The Web UI is updated to reflect the latest changes in the library
• It is visually cleaner
• SSL is now configurable from the Web UI

v1.2.0: Custom LED pin

New features

• You can now set your own LED pin if you don't want to use the built-in LED (#39)
• Option to show / hide passwords in the configuration app (#32)

Fixes

• Setup handlers was called before the MQTT connection was done. This is now fixed (#40)

Misc

• 2 new examples added

v1.1.0: custom branding

New features

• Custom branding allows you to change the default Homie text in the AP name, hostname and MQTT client ID to what you want. Thanks to @vixns

Fixes

• Configuration mode was blocking at boot for ~5 seconds while scanning for Wi-Fi networks. This is now async

v1.0.0: initial stable release

The framework has been tested on real hardware for weeks, and everything is stable.
