Following changes were made in this commit:
--Add quotas to the arrays in the file var/www/data/wrs-data.php
--Change CONFIG_PORT00_PARAMS to CONFIG_PORT01_PARAMS in the
  var/www/endpointcalibration.php. It looks like it was missed during
  interface renaming.
--Change "file" into "firmware" in the firmware input form
--Remove the help when mouse hovers over the form. The help wasn't filled
  anyway (remove title="'.$row["help"].).
--fix part of the shell_exec command: awk '{print $NF}'
  escape the $
--use index 0..5 in the sfpcalibration.php
--remove unlink after calling "rename" function
