[PATCH] scripts: minikconf: support config titles

[Enrico Weigelt, metux IT consult]

Add support for config option titles, like the real kconfig does.
Even though they're not presented anywhere yet (since minikconf
only acts in the background), it's good to have them supported,
so we can start adding descriptions in the Kconfig files.
