Vicamo Yang fa297c4400 Bug 775038 - Part 1: fix various minor defects, r=philikon
* Document Address.decode()
* Merge CharsetEncodedString into EncodedStringValue
* Merge ClassIdentifier into MessageClassValue
* Export missed coder objects and fix test scripts as well
* ReplyChargingValue is defined in MmsPduHelper, not WspPduHelper
* Fix multiple decode test cases data
* Char-set value in EncodedStringValue should be decoded as IntegerValue
* Don't insert per PDU typeinfo into decoded MMS message object
* "Date" is also a mandatory field for M-Retrieve.req PDU.
