Title: Open fields_observed, read in metadata

VPHAS instances can now import **fields_observed*.dat** format files, and based on the VPHAS fields in the file, pull in metadata from my **stats*.fits** files. These are available at http://star.herts.ac.uk/~hfarnhill/vphas/ and can be downloaded directly through a VPHAS instance (user will be prompted for username/password).

Currently the user can specify these files to be anywhere on their system, with the default value being in **survey/data/**. It might be sensible in the future if each instance has a **self.datadirectory** attribute, which the functions can prefer over **survey/data** if present.
