Bug 5176. Record of role changes in a course in nohist_rolelog.db
- Display roles which became active in a course during a specified time interval.
- Display roles which expired in a course during a specified time interval.
- Some wording changes for "version changes" display/interval setting.
- Replace partial phrases with complete phrases to aid internationalization.
- Number of boxes displayed in left column fixed (at four).
