Accept upper case letters in valid_username()

In commit 0722f46 (Simplify valid_user() and valid_username(),
2014-02-06), the conversion to lower case letters was unintentionally
removed and in consequence, names with upper case letters have been
rejected since then.

Instead of reintroducing the conversion, add the "i" modifier to the
regular expression validating the name to do case-insensitive pattern
matching.
