Ability to add custom dependencies to the autocomplete list (VSIX-47)

Originally by @barthamark.

Because the current list is hard-coded. Maybe populate it from an .editorconfig config?

I'd rather have a global set of services (e.g. all Orchard Core services) and all the custom ones in my solution. This is either a VS option or something dynamic like the VS does when you start typing a class name and suggests the name (even if the using is not there and it is in a package).

So like use the types available in the whole solution? But there can be huge number of such types. If we just take the ones available in the current file then that would be a step back from the current list (since you'd need to type them all in).
