this package should be merged to app_manager

[knorth55]

@k-okada I want to merge this package to somewhere and release it, but which package is suitable?
one option is moving this package to PR2 organization, the same as app_manager.
another options is moving this package to JSK organization repositories.

create new repository requires more maintenance cost and we(re not afford to do that.
so, one idea is to move app_manager repository, (in app_manager; mkdir app_manager; mv * app_manager; mv ../app_manager_utils/* .);
other idea is to put under https://github.com/jsk-ros-pkg/jsk_smart_apps
