Feature Request: Aliases for Things and Collections of Things

[emceeaich]

Sometimes one forgets the exact name of a thing, and looking it up defeats the purpose of the assistant.

Enable creating aliases for things so we can be "fuzzy".

Also aliases for groups of things, because the rules system can turn on multiple things, but then you have to work out edge cases (if a => b & c but how do you turn on a alone).

@emceeaich Collections of things will probably be covered by Groups (#1191) but aliases for things is a bit different.
