6df18e2713
First draft implementation of mocks for dream settings. Want to merge for the weekly build, so a few things remain, namely: - flat style for preview/settings buttons + dividers - animation between dream row expanded/collapsed state - wire up the help url - possibly ditch the non-standard style - add logging - refresh when packages are installed/uninstalled Bug:7010260 Change-Id: I96e3ab944170925bd76edf7b8b1127adfffc6262
