Disallow renaming to reserved or existing symbols

[bengolds]

In 1.7, guards were added to prevent users from renaming certain reserved symbols -- you can't rename let or if to something else and you can't rename values imported from packages.

The reverse of this might be handy as well -- not allowing you to rename a symbol to let, or in. It might be nice to also check to see if that symbol is already taken. For example:

foo = 3

bar = 4
-- rename would disallow renaming bar to
--   if, let, else, then, type, alias, module, exposing, and any other keywords
--   foo, since it already exists.
