avoid using octal constants

Using "01" is unwise, since using a leading zero indicates an octal
(base 8) number.
ignore vim swaps
ignore .bundle
use 2.0.0 with rbenv
converted to minitest/spec instead of test/unit with shoulda
refactored tests to use a common helper for loading
oh yeah! failing tests with active support, now to fix ;-)
tests passing now, but no more interval convenience
Tests passing with ActiveSupport, updated README
use to_s instead of to_d for rails support
