Edited the mobile version, added more filters.

• New To read group and tag for stories whose place isn’t known yet.
• Merged stories: the source pills in a story’s header now switch the details between the whole story and one source. Schedule, release calendar and recent chapters follow the choice, each source has its own next check, and Check now works per source.
• Scheduling: a story is never checked before its predicted time. The first look is about twenty minutes after it, with later looks spread over the following days. Stories on a break are checked about monthly (weekly if they show a sign of life), or only by hand after about six months without a chapter. Stories still learning their schedule are checked once a week.
• XenForo threadmark lists with many pages (100+ chapters) are now read in full instead of only their first and last page. Stories read by an earlier version are filled in on their next check, and the older chapters found this way are never counted as new.
• Patreon creator addresses of the form patreon.com/cw/name/posts are now recognised.
• Phone layout: larger tap targets for the source pills and the schedule details stack on narrow screens.
• The “off-schedule check” setting is now “Expected chapter long overdue: look again every”. The default is one week. If you saved a different value earlier, it is kept.
• No new permissions.
