This should probably be tested on another system as well, just to be
sure it makes sense for everyone.
Allows creating an enum with CamelCase to follow Rust guidelines, but
then will match ascii case insensitive. This means variant
SomeEnum::Emacs would match string "emacs".

Breaking Change
Instead of requiring a Vec<&str> for various Arg::*_all() and
Arg::possible_values() methods this
commit now requires a generic IntoIterator<Item=AsRef<str>> which allows
things such as constant arrays. This change requires that any
Arg::*_all() methods be changed from vec!["val", "val"] -> let vals =
["val", "val"]; some_arg.possible_values(&vals) (or vals.iter()).
Closes#87
