Server import

When importing large numbers of files, the transport of the xml files from client to server can be very time consuming.
To alleviate that it is possible, using the file system, to copy the import files straight down to server before initiating the import from the client:

1. The root path for importing files is specified in the configuration file web.config in the <appSettings> section.
   1. Version 3 files: "ImportV3Path" with default value "~/App_Data/Import/V3"
   2. Version 5 files: "ImportV5Path" with default value "~/App_Data/Import/V5"
      
      
2. When initiating an import from the client, if one does not exist, a user folder is created on the server. The name of the folder is constructed from the user's username.
   The username "btr@hafnia.de" becomes "btr_hafnia_de".  
3. To import version 3 files directly from the server, copy the desired files to ImportV3Path/USERNAMEFOLDER.  
   E.g.  "C:\Program Files (x86)\Plass Data\DVI System International\App_Data\Import\V3\btr_hafnia_de".
   
   1.  Start the import from the client
      
   2. Click OK to complete the import.
4. To import version 5 files directly from the server, copy the desired files to ImportV5ath/USERNAMEFOLDER.  
   E.g.  "C:\Program Files (x86)\Plass Data\DVI System International\App_Data\Import\V5btr_hafnia_de".
5. Repeat 3.a. 3.b.
