Moving state_checker and reconfigure_inflation packages from scitos_apps to this repository

Needs https://github.com/strands-project/scitos_apps/pull/95  and https://github.com/strands-project/strands_systems/pull/75 merged.

Used `git subtree` to extract the packages including their history from `scitos_apps`.

Besides moving the two packages I also renamed the `scitos_reconfigure_inflation` to `reconfigure_inflation` to get rid of the misleading `scitos` prefix. A `grep` on the current strands sources showed that no other package is using the reconfigure one and therefore it can safely be renamed.

@raresambrus and @nilsbore, you are the authors of these package, please have a quick look if I messed anything up.
