Attempted fix for #3058: Clicking on view_all_bug_page.php results in…

… 'file download' popup

* config_defaults_inc.php
  (g_compress_html): add a note about coflicts with other compression config
    variable in php.ini

* core/compress_api.php
  (compress_is_enabled): add a check for php.ini methods of enabling compression
    so we don't do it twice
