Add a ROT13 example, testing In/Out channels with libIVC.
Add a run target for the logger example, and remove some accidentally-included binaries.
Fix the implementation of In/Out channels in libIVC.
Remove the libIVC, applications, and PseudoDevice trees from the examples; these examples are either deprecated or subsumed in other examples/test.
Add some (commented out) code to perform sanity checks on block transfers; useful in debugging, but bad for benchmarking.
Rename the 'Misc' examples directory the 'Core' directory.
Updates to the .gitignore files.
