initial take on cap crabgrass:upgrade_to_0_9
fixed error message reporting for old migration
let's keep many releases so one with the old db is still present
make migration work even if there is no notices table yet
properly catch non existing table error

The notices table does not exist in all databases yet. So let's catch the error caused by this.
on update cleanup before running migrations
use a separate branch and directory for testing upgrade
make sure we have a config/crabgrass dir to put the secret in
cd has to be on the same line as the call to rake
deploy:symlink is deprecated
we need to cleanup the old data before running migrations
