#942 Add support for scheduled tasks and commands

This field needs to be at least 31 bits long to store all days in a month.
Other fields are also set to 32 bits because unsigned int length can change
depending on the system.

We also need to support the three ways that the ogAdmAgent and the WebConsole
have to create an schedule. At first, we only supported the easiest
method:
	* Hour, day, month and year -> 10:00, 28, february, 2020

This commit adds these two ways to create an schedule:
	* Hour, week day, month and year -> 10:00, Monday, february,
	  2020
	* Hour, week, month and year -> 10:00, first week, february,
	  2020
