Add --tab, --fields-xxx, and --lines-terminated-by options to drizzledump

[m00dawg]

Currently, mysqldump supports the --tab, --fields-xxx, and --lines-terminated-by options to output content in ways simile to SELECT ... INTO OUTFILE. This behavior does not appear to be in drizzledump, or if it is, the documentation is lacking the explanation of these features (see http://docs.drizzle.org/clients/drizzledump.html).
