[Filesystem] Added few new behaviors:
- add a IOException and a main filesystem exception interface - whenever an action fails, an IOException is thrown - add access to the second and third arguments of touch() function - add a recursive option for chmod() - add a chown() method - add a chgrp() method - Switch the 'unlink' global function in Filesystem::symlink to Filesystem::remove. BC break: mkdir() function now throws exception in case of failure instead of returning Boolean value.
