projects have a list of collaborators
configured test environment
project collaborators can put tips on hold
project collaborators can decide tip amount of undecided tips
only collaborators can change projects and set tip amounts
added author and message to the tip decision table
fixed feature, there should be one email per commit
collaborators can display tipping policies on the project page
switched to the new rails-bootstrap-forms gem
better display of undecided tips
amount given diminishes after each decision (fixes #68)
ensure a collaborator cannot change the tips of another project
update all projects
display nickname first
free tips are not to pay

truncate commit message to fit in database
extra checks to ensure we never give more tips than the available amount
