Responses limited to 1024 characters

[faultyserver]

mpackCPP defines the data buffer for a node to statically be 1024 characters. This means that responses longer than 1024 characters will appear truncated and have an invalid representation.

The easiest (and likely viable) solution would be to expand the buffer to 4096 characters, but the real solution is to replace the implementation with std::string. Both of these require modification to mpackCPP itself, so the std::string solution is probably better to go with now rather than later.
