Case-insensitive property, enum deserialization should be supported

[MikeDombo]

Full Jackson has the option ACCEPT_CASE_INSENSITIVE_PROPERTIES and ACCEPT_CASE_INSENSITIVE_ENUMS, these or similar options should be available for jackson-jr.

Another excellent idea!

Merged but does not work in 3.0 (master) due to implementation differences. Need to think of what to do there: 3.0 would actually have efficient mechanism for case-insensitive matching via PropertyNameMatcher... but needs to be wired. There's an existing comment that suggests caching might be challenging as well.

Was able to make master/3.0 work as well with PropertyNameMatcher.
