The code was a bit messy and didn't make use of namespaces very well.
By converting to a set of functions (instead of a class) I can use
each function as a function pointer if I want to. I am also able to
remove libsaria/library.cpp since this was just a set of wrapper
functions to the old static class functions.
I plan on storing all my preferences there rather than creating my own
save directory. This will keep things consistent with other
applications the user may have.
