* fixes SMART Status "unknown" in the smart widget
This fixes the "Unable to detect device typ" of smartctl, because it needs the full path to the device (e.g. /dev/ada0). As second it removes white space from start of $state variable before return, which let it match in the right way in the smart_status.widget.php. And as last the additional diskinfo command let the script skip devices, where disking exits with the error 'failed, probably not a disk.'.
* replace device listing
replace fixed device pattern with list of disk devices detected by kernel
width, align, valign, cellpadding, cellspacing, border, summary, bgcolor
Error: The width attribute on the table element is obsolete. Use CSS instead.
Error: The align attribute on the table element is obsolete. Use CSS instead.
Error: The valign attribute on the table element is obsolete. Use CSS instead.
Error: The cellpadding attribute on the table element is obsolete. Use CSS instead.
Error: The cellspacing attribute on the table element is obsolete. Use CSS instead.
Error: The border attribute on the table element is obsolete. Use CSS instead.
Error: The summary attribute on the table element is obsolete. Consider describing the structure of the table in a caption element or in a figure element containing the table; or, simplify the structure of the table so that no description is needed.
Error: The bgcolor attribute on the table element is obsolete. Use CSS instead.
* Suppress output when no SMART devices available
Small fix. Prevents empty form dropdowns when no SMART devices are available (i.e. running in a VM with a vdisk)
* use gettext for text
* better conditional check
