Fix seeded Bourreaux

[crocodoyle]

The rake db:seed:dev command is supposed to create a bunch of database entries and files so that developers can test with some data. However, the Bourreaux that are created as part of this process are broken, and cannot be started. The error message that I get:

Execution Server 'Main_Exec' could not be started. Diagnostics:
Remote control command for Main_Exec failed.
Command: cd /Users/adoyle/cbrain/BrainPortal/seeds_dev_support_dir/exec_main; bundle exec ruby /Users/adoyle/cbrain/BrainPortal/seeds_dev_support_dir/exec_main/script/cbrain_remote_ctl start -e development -p 28733 2>&1

The entire DEV seeding script needs to be done right. Mea culpa.
