execute commands in modified environment

instead of sourcing and using the functions directly now it is also possible
to use the functions like this:

  $ALICE_ROOT/PWGPP/scripts/utilities.sh functionName args

it makes debugging easier, e.g.

  bashdb $ALICE_ROOT/PWGPP/scripts/utilities.sh guessRunNumber 000123123
