Use less vertical space for type-constructor hint; 

Also, show it actually for UnknownTypeConstructor, and not
  UnknownVariable. There's currently an error that wrongly assign an
  'UnknownVariable' in place where it should be an
  'UnknownTypeConstructor'. Fix coming in the next commit.

Data-type constructors are not automatically imported, even if their type is imported. So, if a module 'aiken/pet' defines the following type:
┍━ aiken/pet.ak ━━━━━━━━
│ {keyword_pub} {keyword_type} {type_Pet} {{
│ {variant_Cat}
│ {variant_Dog}
│ }}
┍━ aiken/pet.ak ━ ==> ┍━ foo.ak ━━━━━━━━━━━━━━━━
│ {keyword_pub} {keyword_type} {type_Pet} {{ │ {keyword_use} aiken/pet.{{{type_Pet}, {variant_Dog}}}
│ {variant_Cat} │
│ {variant_Dog} │ {keyword_fn} foo(pet : {type_Pet}) {{
│ }} │ {keyword_when} pet {keyword_is} {{
│ pet.{variant_Cat} -> // ...
│ {variant_Dog} -> // ...
│ }}
│ }}
You must import its constructors explicitly to use them, or prefix them with the module's name.
┍━ foo.ak ━━━━━━━━
│ {keyword_use} aiken/pet.{{{type_Pet}, {variant_Dog}}}

│ {keyword_fn} foo(pet : {type_Pet}) {{
