Enum parse enhancement

[ratoshniuk]

Current parse method is case sensitive.

enum CustomEnum {
    Field1
    Field2
}

def parse(str: String) : CustomEnum = {
     str match {
          case "Field1" => Field1
          case "Field2" => Field2
     }
} 

it could be much better to parse lower case. we could use enum values as path prefixes in http routes, for example

def parse(str: String) : CustomEnum = {
     str.toLowerCase match {
}
