Refactor the installer to support multi-install.

The installer now does its work based on distributions and target installation paths.
Each distribution has exactly one target installation path but each installation path can have more than one distribution.

In the absense of the --multi-install switch, the installer should continue to work as before.
The biggest difference here is that we don't rely on a single global distribution object that controls the entire installation flow and we have a few classes for the new abstractions instead of global functions.
It's far from perfect, but it's a step towards separating the core file package required for all distributions from the distributions themselves.

Additionally, there are tons of little changes here such as consistant usage of FilePath and CommandLine instead of mixing them with std::wstring.

TEST=Install, uninstall, upgrade, etc.  Everything install related.
