version 3.5 final

• New feature: Using the *.tpy file generated by TwinCAT it's now possible to
  access single elements of structures and arrays and also internal variables
  and parameters of FB's. Structures definitions are built automatically if no
  definition is provided by user. Target information like NetId and port can be
  read from the file, it's no longer necessary to set them manually.
• New feature: Just like the symbol table, the data type information can be
  im-/exported from/to a JSON string. Especially intented for Tasker scripts.
• Changed API: New client parameter "configFileUrl". The path to the *.tpy file
  on the webserver.
• Changed API: New client parameter "forceUploadUsage". Skips building the
  symbol table from the data of the *.tpy file and use the Upload instead.
