Micropub query config support to auth.php. Improved parse_hcard
in SimplePie Parser to also cache photos in h-feeds, and
parse_hcard helper function in microformats.php will now add photos
from reposts to the nickname cache. Invoice and Purchase modules
now operate from the assumption that dates for a given day can have
timestamps anywhere between 00:00:00 and 23:59:59 on the day given.
Fixed a bug in Purchase module that was using a 12 hour window to
check purchases rather than following the new rule for timestamps.
Stock module bug made items that were available to purchase
unavailable from the supplier, which meant they no longer showed up
by default on the stock page. Other changes are small UI improvements.
