Added support for php+-mode
Clean up php+-mode hook to be local. Update changelog for 1.0.5.
Made `flymake-phpcs-standard' more safe.
`flymake-phpcs-standard' is only safe as a local variable if the
specified standard is not pointing to a file/path to a standard.

So the safe-local-variable property is adjusted to only be safe when
the value is string-or-null-p AND it is not file-exists-p.

This might fail in the case where you specify i.e. PEAR as standard
and also have a file or folder named PEAR relative to the
buffer. PHPCS will choose the installed standard but
flymake-phpcs-standard will consider the setting unsafe. At least it
only fails to the safe side - it won't allow unsafe values but can
mark a few safe values as unsafe.

Another approach would be to only accept all installed standards
(phpcs -i) as safe values.
