a LOT of things (read description) I might not list everything in this commit but: - fix struct stream operators while making them a bit less convenient - refactor some stuff around like the FOR_EACH macros - fix 2/3 minor bugs I stumbled upon when actually trying to compile

refactor a huge part of the code this allows for creating only input and output streams and allows me to finally print out the generated config struct

fix pretty much everything, read description this is a big (or dare I say, huge) commit that pretty much fixes every problem I've had so far with the basic parsing I still need to do a custom operator>> for some types but at this point the parser goes through the entire file and prints out everything which is a large milestone I'd say changes in this commit: - add SECTION_LIST for a section containing a single list of values examples: TimingPoints, HitObjects - improve operator>> for enums making it accept int values and fail properly when the value is incorrect (there's a warning I need to get rid of but it's ok for now) - skip over blank lines: adding this single line (src/osuparser.cpp:52) made the parser go from shitting itself to actually going through the whole file and printing everything (with some errors but still) - new string util: isBlank() used for the above - new __VA_ARGS__ util: ARG_COUNT() and rename foreach.hpp to va_args_util.hpp as that name no longer fits
