Clean conversion cache

The application comes with integrated file conversion cache. 

File conversion cache is stored in the file system, by default into $TOMCAT/repository/cache folder.

A classical example of document conversion is generating the thumbnail of each document shown in the default application user interface. For example to get a thumbnail of a Microsoft Word document is needed convert the first page as an image. For doing this process application consumes some CPU.

To prevent it consumes more CPU than necessary, the documents are converted only when it's necessary, first time, or after document update. In other cases the file is retrieved from cached files.

The administrator can take control of these cached files and clean by type or all.
