Title: Refactored random string generation.

The method of string generation was not really optimal and it ate up to 20% of the CPU time while loading data into TPCC database.

After refactoring the java cpu load while loading decreased dramatically. Futher the load times for 8 warehouses decreased from 5:48 to 4:51 on my machine.
