Extract default settings to its own file.
Set CANONICAL_HOST to its default, localhost:8537

* This comes directly from the README.
Fix Windows environ[] = '' edge case.
Revert CANONICAL_HOST change in favor of fix.
Update README to reflect actual default config.
Rewrite gittip.py:

* Windows support
* Remove fabricate
* Include a docstring
* Create local.env from default_local.env
* Only execute each step when specific files are missing
* Use __name__ == '__main__' convention for potential reuse
* Have it check for 'pg_config' sooner for cleaner error message
Remove '.' from requirements.txt since:

* It's taken care of in Makefile
* It's taken care of in gittip.py
* Uses '-e .' in those other places

Implement UI for recording manual exchanges; #53

Sometimes we do manual payouts (maybe payins someday?) and we need a way
to record those in the database so we don't have to keep doing them
directly in SQL(!). This adds a form to the history page for site admins
to use. It extends the exchanges schema to keep track of who made manual
adjustments and why.

Fix width on distribution bars; #620 == #701

This isn't my favorite distribution ever, would love to replace it. But
for now we should maintain it.

Redo logo to match coin

I tried really hard to make the heart in the pennies match the heart in
the logo. We didn't quite get there, so instead I'm making the digital
logo match what we're getting in metal. Kinda easier that way. :)

Rationalize the CSS for nav

The box that's front and center in the visual design has three levels
for nav. Rather than classing all of these levels as "buttons" and
distinguishing them as "tips," "nav," and the one-off "rip," now we
class them all as "nav," and then use "level-1," etc. for the three
levels.
