DB now holds money entries in cents

DB now holds money in cents, but still the entry in the migration is dollar_amount.

!!! getters for accessing dollar amounts in donations and projects are now required and automatically convert cents to dollars !!!

!!! A little quirk now added because of the cents transition. Whenever we auto populate a form_for, the dollar amount will be filled with cents value......meaning upon editing a (project or donation) the dollar field will be 100x what it is suppose to be.

The save and update of (donations, projects), the (donation.dollar_amount, project.dollar_goal) is automatically converted to cents and stored into the db.
