- fix for issue 772

- 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
