Correct 'libs' path to 'lib', and correct the commented-out parameter order in object initialisation

Attached are two very minor patches that make things easier for new users.

The bin/read code incorrectly searched for the PBTreeDictReader object in the 'libs' directory, instead of 'lib'.

The bin/remote_read code had two commented-out parameters at the first two parameters of the object initialisation, when it should actually be the last two parameters.
