Automatic preference/key name generation from class/field name

[yshrsmz]

Currently we need to manually define SharedPreferences name and key name, but what if we can generate these name from class/field name?

for example

@Pref
class Sample {  // preference name will be "sample"
    @Key
    long longValue = false;  // key name will be "long_value"
    @Key
    String stringValue = "default_value";  // key name will be "string_value"
}

logic is quite simple, just convert CamelCase to snake_case.
Of course we can still provide custom name with @Key(name = "key_name")

NP!
@yshrsmz Ah, actually rxjava2 branch is the latest, so can you reference the branch rather than master?
