updated dev documentation for Mac OS X Mavericks users
ignore `reflex` on orphan steps, refs #238
Prevent inactive popovers upon rapid navigation. refs #188
handle window.localStorage being unavailable

Some security settings (Firefox 'always ask' cookie setting)
may result in accessing window.localStorage
raising SecurityError.

Setting this as the default, even if unused,
makes it impossible to instantiate a Tour.
Don't set current step to 0 when restarting a tour
Check working step is still the current step in _scrollIntoView

One can end up with multiple stalled popovers all over because scrollIntoView can some times take a while to end (and current step could have changed by the time), so do not assume the current step is still the same and do not show overlay or do things if the current step has changed since scrollIntoView started.
