rafactor timeslot/availablities

[remipichon]

• term accuracy only defined the availabilites accuracy.
• add 'strict' mode which is what we have now
• for timeslots, accuracy is default calendar accuracy but can be changed from 0.2 to 4.
  • how to display timeslot that doesnt fit the selected accurary on the calendar ?

rename 'creneau' to 'calendarSlot'

todo

• conf-maker
  • assignment term
  • add 'non-strict' mode where timeslot can be created freely
  • 'strict' mode is default, timeslot will have to match accuracy
  • 'strict' to 'non-strict' allowed, not the other way around
• task-maker
  • timeslot
  • calendar
  • on non strict term, allow to set another accuracy
• assigment
  • timeslot calendar
  • userToTask
  • taskToUser
  • on non strict term, allow to set another accuracy
    • taskToUser: worthless
    • userToTask: allow to select quarters instead of hours (shit shit shit)
  • review both assignment mode helpers workflow
• user-maker
  • should support avail with term in middle that doesn't fit accuracy
  • how to allow/deny updates ?

wrapping up

• review both assignment mode helpers workflow
• clean code

Tests remaining

• non-stricte with timeslot from previous day (midnight thing)
  • margin-top should not even be concerned
