I used this chance to make some name changes, add some utils, tweak some imports, remove more `setTitle`s and so on. I also made person, repo, key and project creation forms verify CI-uniqueness.

-- | CI views for avoiding ambiguity in the meaning of some typeclass
|
|
-- instances, and allow two instances to coexist. For example, does 'show' show
|
|
-- the original or the case-folded version? Using CI views, it's easy to
|
|
-- specify that.
|
|
--
|
|
-- Note that some of the instances provided here, i.e. instances 'CI' already
|
|
-- has, are reused directly by both views. If you aren't sure about a specific
|
|
-- instance, check the source.
