Added .cc file for classes/structs that only provided by header
file. Defined non-POD classes' ctor, dtor in .cc file. Moved
implementation code in header file to .cc file for major
classes/strucsts.
Added keys parameter to aria2.tellStatus, aria2.tellActive,
aria2.tellWaiting and aria2.tellStopped XML-RPC method. 'keys' is
array of string. If it is specified, the response contains only
keys in 'keys' array. If 'keys' is empty or not specified, the
response contains all keys. This is useful when you just want
specific keys and avoid unnecessary transfers. For example,
*aria2.tellStatus*("1", ["gid", "status"]) returns 'gid' and
'status' key. Made get*Param() functions XmlRpcRequest's
methods and changed portions of the code that were affected by
this change.
