- renamed database to connection to better identify what it is (would database_connection be better though?)
- moved basic_statement and basic_transaction to sqlite::detail
- made sqlite::threadsafe() return the threading mode int, not a bool
- renamed row::index() to row_number() so it isn't confused with column index
- added typedef for deferred_transaction
- added early rollback method to transaction_guard
- allowed transaction_guard::~transaction_guard() to throw exceptions, since when it needs to, we're really screwed anyway
- bugfix: query::reset() didn't reset the internal row counter
- added query::num_results()
- added docs/design-notes
- reimplemented query::iterator so that increment() (which performs a step() on the query) now caches the returned row to be returned during dereference() (previously it stashed details and returned new row!?)
- bugfix: resetting active queries during rollbacks would hang!
