php7 and stdout

[markkimsal]

my copy of php7 cli does not put syntax errors onto stderr.

PHP 7.0.12-1+deb.sury.org~trusty+1 (cli) ( NTS )

I had to make this change.

87 " Run the PHP linter to check for syntax errors
88 function! Phpqa#PhpLint()
89 if &filetype == "php"
90 if 0 != len(g:phpqa_php_cmd)
91 let l:bufNo = bufnr('%')
92 call s:RemoveSigns()
93 "let l:php_output=system(g:phpqa_php_cmd." -l ".@%." 1>/dev/null")
94 let l:php_output=system(g:phpqa_php_cmd." -l ".@%." ")
95 let l:php_list=split(l:php_output, "\n")

I think this also fixes the vim-fugitive problem.
