Feed update scheduling

I want to be able to define in my feed aggregators when a feed or feed group should not be checked for updates.

When I attend a conference or I am at work I am focused on groups of feeds. Please only update those groups automatically until after 6 p.m. Monday through Friday. I know audio from Fresh Air will not be available until 4:30 p.m., so there is no use in teasing me at 10 a.m. while I wait for the audio.

Similar to ttl each aggregator could use skipHours or skipDays as the default and not let me override the feed data, but I should be able to add my own viewing habits or knowledge of the source for a better experience as well.

I ran the idea by Nick Bradbury last weekend and he said it made sense but he had never thought of it before. Hopefully I can control my feeds better and take a load off the publishers by knowing their feeds better than they have described them.
