[docs/Perl6/Spec/IO.pod]  - add some initial organization by adding "File, filehandles and directories" section, based on Perl5 perlfunc  - Created "unfiled" section for the rest of the functions for now. perl5 perlfunc    could provide further inspiration on how to organize these.  - Documented the first function, chmod, by doing 'perldoc -u -f chmod'    and copying the POD over. I trimmed out the 'fchmod' and 'fcntl'     sections because I wasn't sure how/if they applied to Perl 6.    If you know better, please add them back in with appropriate    adjustments.
