- fixed -Werror=misleading-indentation warning
- fixed -Werror=nonnull-compare warning on xll and QT builds
- PNG_LIBPNG_VER backward compatibily changes
- giflib backward compatibily changes
- resolved some undefs for X11 build
- silenced some small compile warnings in JGE Makefile
- added -DTIXML_USE_STL to remaining build types (PSP had it added)
- fixed x11 Boost incompatibility issue part of #548
- reworked PrecompiledHeader.h platforms used
- fixed some issues in zstream that prevented to use "getline" in zipped streams
- added a "pooled buffers" system to keep a cache of file descriptors. This is potentially dangerous though, but shaves several seconds of loading time on the PSP. If problems arise on other platforms I'll make it a compilation parameter
- gracefully fail when calling manacost information on a not properly initialized mana cost
-- 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.
