Wire up the advanced installer to a button in the UI

[halgari]

A horrible hack, and some other fixes:

• Updates the spine VM to log an error and not crash when Skia fails to load an icon
• Switch to PNGs for the game icons the JPG files were crashing for some reason (resolves Skia crash after upgrade #717 )
• Adds an optional parameter to ArchiveInstaller.AddMods so you can force it to use a specific installer
• Registers the AdvancedInstaller as an IModInstaller
• Adds a button to the LoadoutView that will find the advanced installer and use it to install a given mod.
• The way we find the advanced installer is a very ugly hack, but until Unnecessary Project Dependencies: Introduce Abstractions or Common Package #207 is resolved we can't do this easily
