calendar working copy
Introduced calendar with marked dates and list of transactions by day.
1. Calendar tab with ability to view, add, and modify transactions.
2. Recurrences now extend out a year.
3. Transactions tab only displays up to present date now.
4. Categories tab displays last 30 days of categories
5. Code refactoring - use of NSDate convenience routines
6. Cleaned up transaction cell view.
Fixed issue in transaction view controller that prevented the merchant auto-complete from displaying results from the expected date range.
