-- zipFS has several limitations... --- in a general way, seekg doesn't work... so getting a file's size needs to be done through JFileSystem. --- getLine on files open with zipFS doesn't work so great. Not sure if it is a normal issue because files are open in binary or not... JFileSystem therefore offers a "readIntoString" function that needs to be used instead of the usual "getline" technique. However getLine can then be used on a stream connected to the string. -- tested on Windows and PSP, I also made sure android still works, but haven't tested zip support on Android. -- I tried to maintain backwards compatibility, but this might break on some platforms, if I broke some platforms and you can't find a way to fix them, please contact me and we'll figure something out -- This removes wagic::ifstream. I didn't reimplement the securities that were involved in this, apologies for that. Might be useful to reimplement such securities in JFileSystem -- I haven't tested options/profiles in a deep way, it is possible I broke that.
