[ui:cwd] fix #1433 create a thumbnail of the video file with ffmpeg

Browse Source 
Added volume root options
```php
// Video to Image converters ['TYPE or MIME' => ['func' => function($file){ /* Converts $file to Image */ return true; }, 'maxlen' => (int)TransferLength]]
'imgConverter'    => array(),
// Max length of transfer to image converter
'tmbVideoConvLen' => 10000000,
// Captre point seccond
'tmbVideoConvSec' => 6,
// Resource path of fallback icon images defailt: php/resouces
'resourcePath'    => '',
```

It can specify a specific number of seconds part in the file name.

e.g.
xxx^[sec].[extention] -> video^3.mp4
