Move reusable modules into a .util package
Add basic Flask-Script functionality and make the app take a config file on creation
Use Flask-Migrate to manage Alembic

Had to work around some craftiness, and I might eventually submit a pull request to fix that once this is all done.
Move management executable into the evesrp package

Also install an 'evesrp' command line utility for accessing the management interface.
Have the app look for certain environment variables on startup
Remove debugging statement from manage utility
Trick Alembic into ignoring __init__.py
Add migration script for enforcing a minimum base_payout of 0

Should've been committed with c817d4df
Migration: rename action._type column to action.type_
Add a management command to create database tables
Migration: change request.base_payout from float to numeric (decimal)
Migration: split Modifiers into two subclasses
Move+rename create_table management command

It's now under the 'db' subcommand, and it just 'create'. It also only creates tables for fresh databases.
Merge branch 'flask-script'
