Stable version promoted to v1.0.0
v0.8.0 is working for weeks on my tablet and is considered as stable.
In parallel, I'm planing for major architecture changes, justifying a version bump.
Consequently, v0.8.0 is promoted as v1.0.0
CAUTION : this version is still suffering for memory corruption if Lua's callback is called when an MQTT message arrives. In other word, using "trigger" is safe, "func" isn't ... yet.
