I had particular problems with Ctrl-N (open new window/tab)
interfering with N (go to next unread item). This change
disregards keyboard shortcuts if Alt, Shift, or Ctrl are used.
It also tries to disregard Win/Super/Meta, though this didn't
work for me in Firefox. Still, just the Ctrl is an improvement
for me.
Inserts a (unread/total)" items count in front of each subcription
on the feeds page.
models/feed.php adds two functions: get_feed_unread_counts(), get_all_w_counts().
get_feed_unread_counts - returns either an array of (unread/total) counts indexed
by feed id or a singl (unread/total) for a specific id.
get_all_w_counts() returns the same as get_all() but appends items_unread and
items_total columns.
controller/feed.php modifies Router\post_action('refresh-feed',function() to
retrun the (unread/total) count in the retruned ajax json array.
Router\get_action('feeds',function() was modified to call get_all_w_counts().
templates/feeds.php was modified to insert the (unread/total) count into the
span id="loading-feed-" such that is can be updated after a refresh.
assets/js/feed.js was modified to to have the Update and hideRefreshIcon
update the returned (unread/total) amounts in the "loading-feed" span.
