Code Issues Proposed changes

Store topic of a change in Notedb

Browse Source 
This adds a 'Topic' footer to  the commit messages of the
refs/changes/XX/YYYY/meta notes branch when the topic changes.

Similar as for hashtags we cannot rebuild the history for topic
changes since the database only stores the current topic.
