Fix multiple notices discovered while developing System Log

Fixing multiple notice types:

• Only variables should be assigned by reference
  • function result is passed directly to array_shift function
  • kApplication::recallObject result assigned by reference
• Undefined index: name - custom tag on shipping costs page
• Undefined index: mode - custom tag on shipping type groups page
• Undefined index: title - incorrect definition of "inp_edit_fck" block
• Undefined index: t - wrong template manipulation in adm_PrintSection tag
