info: highlight formula and cask installation status (✔/✘)

[HaraldNordgren]

brew info to display installation status indicators for formulae and casks. It's not at clear as it could be now, so this would be a good improvement.

The output shows a checkmark (✔) for installed formulae and a cross (✘) for uninstalled formulae, same as already happens for its dependencies.
