Title: Slack notifications

Implements methods to check if the person is late to work:
`late?(shift)`
if he/she missed work:
`missed_the_day?(day)`
and to check if the lunch break was too big:
`break_too_long?`
In case of any of those happen, an slack notification will be sent to `#cagou_no_pau_no_ponto` according to the case of the event.

``` Rake check_absences:yesterday``` will run daily to check people who missed work on the day before
