Added an overloaded method with just one argument and deprecated the original one.

> KCodecs currently provides only decodeRFC2047String(), and even that has a comment saying "more robust implementation available in KMime". This patch makes KCodecs::decodeRFC2047String() use the "more robust" implementation from KMime, and adds KCodecs::encodeRFC2047String() counterpart - also using implementation from KMime.

I believe that having a proper and more robust implementation available in a more generic framework like KCodecs is better, than if it was hidden in the KMime framework. As a result, we can make KMime framework to use KCodecs (it already depends on it anyway) for all the encodings, and only leave classes for storing and parsing the "high-level" message/rfc822 messages, and headers. It also reduces code duplication, and makes all applications use the same encode/decode implementations (which is cool, right? :-))

I believe that this is a rather useful tool that could find wide adoption outside PIM, therefor I decided not to move it from KPimUtils to KMime, but instead move all the interesting, and multi-purpose parts from KMime into KCodecs.
