4f2e0c6d7f refactor(frontends/lean): add 'attribute' command 
The new command provides a uniform way to set declaration attributes.
It replaces the commands: class, instance, coercion, multiple_instances,
reducible, irreducible

752b54085b refactor(kernel/type_checker): type checker should not unfold macros, but sign an error if a untrusted macro is used 
Now, we unfold untrusted macros outside of the Lean kernel.

ca632cca13 feat(frontends/lean): add 'universe variable' command 
We can declare variables anywhere. So, we must also be able do declare
"universe" variables anywhere. Here is a minimal example that requires
this feature

```
-- We want A and B to be in the same universe
universe variable l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B
```

The following doesn't work because A and B are in different universes
```
variable A : Type
variable B : Type
definition tst := A = B
```

The following works, but tst is not universe polymorphic, since l is
one *fixed* global universe
```
universe l
variable A : Type.{l}
variable B : Type.{l}
definition tst := A = B
```
