Heroku command-line wrapper with app name

This is a kind of second version of https://gist.github.com/4208338, but in this version you don't need to call projectName_production or projecName_staging only production or staging.

How to make it work

If you have git remotes called production, staging and development already, then then the only thing you have to do is to source heroku_command_line_wrapper_with_app_name.sh in your .bash_profile or .bashrc:

source /path/to/heroku_command_line_wrapper_with_app_name.sh

or

. heroku_command_line_wrapper_with_app_name.sh

If you want to use your existing git remote names, then create a .herokurc file and put the following variables on it:

heroku_production_git_remote=name
heroku_staging_git_remote=name
heroku_development_git_remote=name

Usage

$ cd /dir/with/a/heroku/app

$ staging logs 
$ staging logs -t
$ staging config:get MONGOHQ_URL
$ staging run console

$ production ps
$ production logs -n 3 -p worker.4 -s app -t

You should know the production, staging and development bash functions will be available all over the place, but if you call one of them in directory not containing a heroku application you'll get an error like ! Resource not found or something like that.
