FileTransfer reworked (first steps - functionality as is), HttpUpload

separated, some bugfixes
- HttpUpload moved into own package
- FileTransfer managed by a central manager class, several
  FileTransferService implementation can be used
  - Security initializations moved to ConversationsPlusApplication
  - Access to PowerManager moved to ConversationsPlusApplication
  - Removed unused code fragments
  - Access to HttpConnectionManager is now static
