act: Add more command names and implement GetErrorCode (#237)

* act: Add more command names and implement GetErrorCode

The command names have been extracted from 3dbrew and the JavaScript
bindings that the NNID settings uses internally.

The error names have been extracted from the Wii U implementation
(102-XXXX), which are compatible with the 3DS ones except for 022-5XXX,
which are error codes specific to the 3DS.

* act: Split error codes into separate file
