1.1.6 beta

### 1.1.6 beta
Note: This is a beta version, because not all of the javascript ajax functions have been tested yet.
- Added the following to [**Advance Duplicate File Menu**]
  - Scene cover preview image option
  - Webp preview video option
- Fix json string return for all calls made from javascript.
- Added DupFileManagerPyVer field to json when called from javascript.
- When deleting scene using Report, replaced completion prompt with scene background set to gray.
- In Report, when rename occurs, the scene gets renamed inline, without having to reload report page.
- Added GetRunPluginOperationJson to DupFileManager_report.js which allows result to safely be converted to json. If fails, it gracefully returns null.
