This commit modifies InfoResult to remove all of the omitempty tags since
the fields should be present in the marshalled JSON regardless of them
being zero values or not.
This commit modifies the types of the GetMiningInfoResult to better match
their underlying types. While the information was all available and
accurate, it's nicer to treat numeric values as proper types instead of
all float64s.
Also, a new networkhashps field has been added for compatibility with the
reference implementation.
This commit extends the RegisterCustomCmd function to also accept a reply
parser which will be invoked for replies to the custom command via
ReadResultCmd. This allows replies to custom commands to be returned a
concrete structs instead of map[string]interface{}.
ok @jcvernaleo, @jrick
This commit moves all of the structs which deal with command results and
related functions to a new file named jsonresults.go.
This is in preparation of allowing custom results to be registered.
ok @jcvernaleo
