Better compatibility with different servers

This is a set of changes to make MoulKI compatible with more servers, specifically MOSS and Minkata:

- Send requests in an order that more closely matches plClient (MOSS has stricter requirements on their order than apparently other servers).
- Support Server.Auth.G and Server.Game.G settings in server.ini (Minkata uses nonstandard values).

I also updated the build number to 918 and added more error checking for a case that I ran into while debugging H-uru/libhsplasma#33.

Requires H-uru/libhsplasma#31 and H-uru/libhsplasma#32.
