* minor optimizations - using "const &" to avoid creating a duplicate for function arguments in the library files
* nandBin needs to be built with write support to create a new file
* fiix bug when writing supercluster
* add macros for nand attributes
* adding another example program for creating nand.bin and adding wads. it SEEMS to work as expected, but still, use it with EXTREME CAUTION
* changed default NUS_Cache path in NUS downloader to parent directly so the 2 example programs can share the same cache
* added "-all" argument for the nandBinchecker
