Readme error in calendar_for example

[alexfeseto]

The first calendar_for example in the readme will output a misleading / inaccurate calendar, owing to the default value of first_day_of_week being 0 (i.e. Sunday).

I think the doc should either read:
<%= t.head('sun', 'mon', 'tue', 'wed', 'thu', 'fri', 'sat') %>

Or show the first_day_of_week symbol being passed:
<% calendar_for(@tasks, :first_day_of_week => 1) %>
