(chocolatey#23) Disable install all keyword for alternate sources

This throws a not implemented exception if the all keyword is used with
non-nuget alternate sources. This is because the all keyword only has
handling built in for normal sources, and it is better to throw an
error than to have the source try to install a package called "all"
