feat(init/meta/interactive): suffices tactic
...
Just a simple manipulation of the `have` tactic, but it allows the use of `suffices h : T, from p,` in tactic mode.

feat(src/kernel/error_msgs): show aliased variables when printing error messages

closes #1814
@kenmcmil: the error messages will now list aliased variables.
For example, in your file, the new error message is:
```
invalid type ascription, term has type
triple (ctxpre c' s_1 ∧ ctxpre c'_1 s_1) (bndngapp b s_1) (ctxpost c' s_1 ∧ ctxpost c'_1 s_1)
but is expected to have type
triple (ctxpre c' s_1 ∧ ctxpre c'_1 s_1) (bndngapp b s_1) (ctxpost c' s_1 ∧ ctxpost c'_1 s_1)
types contain aliased name(s): c'
remark: the tactic `dedup` can be used to rename aliases
state:

feat(init/meta/interactive): cases with equality
...
This is the equivalent of the `ginduction` tactic for cases, but rolled into the same syntax as `cases` itself. `cases h : term` is the syntax, and it will introduce a hypothesis `h : term = C a b...` demonstrating that the original term is equal to the current case.
I considered the possibility of calling `injection` on the generated equalities, but it's useless in the casaes when the equality carries some real information (such as `f x = C1 a`), and when the input term is a local constant, `injection` will do subst, which will undo the effect of the `cases`. If the input term is a constructor, then `injection` would do something interesting, but you would never want to call `cases` in this case because the constructor is already exposed.
