Added support in daily tasks for specifying ’every X days’ and ‘every X weeks on specific days of the week’.

- shouldDo() now takes the entire task as an input instead of just the ‘repeat’ (days of the week) dictionary.
- the ‘start’ date for a task can be specified (and can also be in the future, in which case it will be greyed out until then.) ‘start’ date also affects ‘every X days’ and ‘every X weeks’.
- no migration code yet.
