Fixes for roommanager library
The version of the roommanager library originally set in your repositories as a submodule contains various bugs:
- The functions roomman_add_persons() and roomman_remove_persons() were misspelled (missing an ‘m’ in the prefix).
- The functions roomman_update_capacity, roomman_add_persons(), and roomman_remove_persons() are broken.
- The function roomman_clear_reservation() is not working correctly.
All bugs should have been fixed in the latest version (4adc353ad6d979f30b7e513457c710ba104a8bf1). This version has been set in your repositories. A git pull followed by a git submodule update should suffice.
