Don't force building recovery - fixing a 4.4.3 merge derp

Some devices don't have a recovery.img - for example, Xperia Z etc.
This patch comments this out, as it was before the automerge

Some changes added to compile and run with Java 6 and Java 7.

  - correction of errors with Javac 6:
    - target 1.5 and source empty.
  - correction of errors with Javadoc 7:
    - strange behavior when duplicate classes are given.

repopick: Add a way to checkout instead of cherrypick

This helps if you want to take a commit and its dependencies, and not
just a particular commit

repopick: Allow picking batch of commits with the same Change-Id

Gerrit does allow assigning the same Change-Id for multiple commits. This patch allows picking them properly.

repopick: Don't redirect stdout on --quiet

For some reason, when --quiet is specified (example:
repopick --quiet -c 7834), git ends up in /home instead
of the actual repository.

This is a quick workaround until a proper solution is found
