[FEATURE] Added composer locking command
[FEATURE] track picked changes in beard.lock

This commit adds a new file beard.lock when it picks
changes to track the commitHash of the local commit
in relation to the original commitHash of the remote
revision. previously this was done by "littering" the commit
message with lines like these: "(cherry picked from commit...)"
this is now a thing of the past.
[FEATURE] Add GerritTopic Support

This commit adds support to apply changeSets
from a whole gerrit topic into all package directories
that exist.
