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.

With window support

v0.6.2

Add Surface:GetFont()

Stable when using internal callbacks ...
