Add a level of indirection to the implementation of \p{InFoo}

so that we don't have to have long filenames.  (Nothing changes
in the user interface.)   The indirection is defined in
the file lib/unicode/In.pl and it is handled in lib/utf8_heavy.pl.
Also rename some the character classes by removing '-' from
the classnames, and finally renamed Block.pl as Blocks.pl.
