Remove highlights from a syntax file

the commands:
	hi jediFunction ...
	hi jediFat ...
    should not be used in a syntax file.  They belongs to a colorscheme
    script.  When they are present they reset colors set by
    a colorscheme script after openning a new python file when
    after/syntax/python.vim is executed (and a colorscheme script is
    not).  The default values should be set by 'hi def link' command.
    I set the default to
	hi def link jediFat Pmenu
	hi def link jediFunction Pmenu
    since Pmenu is used in a similar situation.
