Released gem includes "generic" development scripts

[ghost]

Two scripts are declared as bin files in the gem specification, I
think maybe they're part of a generated template, and maybe supposed
to be deleted or renamed as we need, but not meant to be released with
the gem. I couldn't install the gem, because currently I have another
gem which seems to have the same issue:

$ gem install timestamp_api
timestamp_api's executable "setup" conflicts with factory_girl_rails
Overwrite the executable? [yN]  ^CERROR:  Interrupted
zsh: exit 1     gem install timestamp_api

Here is the most simple fix/workaround I used: tjouan@855085c
