Minor fixes:

* Ensure that php linter pattern does not include spaces:
    PHP can return errors with extra spaces like the following:
    `PHP Parse error:  syntax error, unexpected end of file in t.php on line 4`

* Set option locally to buffer

* Rename noErrors variable according to the project's naming convention

* Make the jsonlint pattern a little better
