Title: Fixes to goals/totals/etc.

For the most part, this is an update to rename methods to match their updated designs. In the process, the correct values replaced some incorrect ones.

Specifics:
* `total_donated` is the amount (in cents) from donations, including real-time. This does not include community contributions
* `total_raised` is the amount (in cents) from donations and community contributions
* `total_cost` is the amount (in cents) of the fund raising goal + the community contributions (i.e. the sticker price on whatever is being bought/built)
* `percent_xxx` is the amount as a percentage of the total cost
* moved `humanize_amount` into a template tag; renamed to `humanize_cents`
