Hi Felix,
Here is some explanation for this pull request.

• fixed bug in Terminal mode: barcodeTerminalAsync.php and lib_language_en.php
  while doing inventory for a container (inventory mode or "Set storage
  for all following containers"), if you scan a non-existing barcode,
  the location will be removed. When a non-existent barcode is scanned,
  an error pop-up window appears.

• modified History log text to add storage_name; also added History log text
  when changing storage in edit mode (lib_db_manip.php, lib_db_manip_edit.php)

• import.php, lib_import.php: added importing function for locations and
  users using tab-separated text file

• lib_import.php: fix for importing chemical_storage_barcode bug.
  When import tab-dilimited text file of chemical containers, if the
  barcode column is the last column, it will add white space or \n
  character, making the barcodes inaccurate. The fix will trim all the
  white space (\t\n) on the right side of the input column

• lib_language_en.php, sidenav.php, barcode_autogeneration.php:
  Creating option for admin user to auto generate all location and
  user barcodes while using "Existing barcodes" functions

• lib_db_manip.php: edit logging text to reflect chemical containers when
  being moved from one location to another

• Fixed "Set storage for all following containers" in Terminal

• Added barcode Type 128 generation for user using existing barcode

• import.php, lib_import.php: Fixed added order_date and open_date in
  Import tab-separated text file function
