Multiple users using scripts connected to one database

[MichaelGoodale]

Currently, all of the scripts from the SPADE repo, only work if the user running the scripts is also the same user who created/ran the database.

This occurs because during the import process of pgdb, files must be overwritten and the user will not have the correct permissions do this. Unfortunately, who ever runs the script first will own the entire database, and no one else will be able to overwrite their files. (Since the SPADE scripts do the file editing "directly", i.e., without API requests)

This is the cause of MontrealCorpusTools/SPADE#10

This could potentially be fixed by making the import process be more loose with file permissions.
