Rename "Weekdays" to "Days of the Week"

[Blucose]

When setting a time trigger (and potentially elsewhere) the box at the bottom shows the hint of "weekdays". In English this implies Mon-Fri (i.e. not weekend days). This makes it confusing when editing a trigger, because the assumption is that it will only trigger on Mon-Fri in it's default state.

"Days of the week" would be a more appropriate label for this.
