USES=lua gained flavors.
Ports using USES=lua:module or lua:flavors will be flavored. A range of
supported lua versions can be set using XX-YY (or XX-, or -YY, or simply ZZ)
for ports not supporting all lua versions.
USES=lua sets LUA_FLAVOR that needs to be used on all dependencies of
flavored lua ports, in a similar way as PHP or Python flavors.
