Default edit ui should be provided automatically for trivial types

[Wumpf]

Many types are just variants of enums, floats or integers. It shouldn't be necessary to manually add editors for all of these!

Note however, that we always want a way to override them. For instance floats often have various valid ranges (affecting ui clamp) or preferred ranges (affecting ui speed), so it's important that a "auto ui" is never locking us in to anything!
