issue #1580 Add last calculated cache size to Dashboard Storage chart
Size of cached files with all derivatives and representatives may be
as large as all image files, actually doubling the needed storage
size. So it may be nice to see it represented in the storage
chart, if one remembers to occasionally recalculate it under
Tools -> Maintenance..
Also make it possible to deactivate this setting.
* at the end of the upload of after a maximum duration, move the photos from the lounge to their actual categories.
* do not invalidate user cache when photos are added in the lounge, thus avoiding to rebuild cache on every photo uploaded
* the lounge system activates itself only beyond 50k (by default) photo
* new conf setting related_albums_maximum_items_to_compute (1000 by default). Beyond this number of photos in current set, do not try to find related albums.
* new conf setting related_albums_display_limit : only display the heaviest (most related) albums.
* use configuration setting quick_search_include_sub_albums (default=false) to activate this feature.
* the list of sub-albums is not displayed in the list of album results (to avoid too long lists).
* Number of weeks for Activity Chart is now in configuration file
* Tooltip change for activity chart and add for storage chart
* General page design change
* Number of years compared is a configuration variable (default 5)
* Months compared are the actual, the last and the actual month the last year (you can also visualize the average last 12 months)
This commit introduces a new config var and a minor change in a tpl
(language key switch)
It also change the default behaviour; can be set back to the previous
one with $conf['menubar_tag_cloud_content'] = 'current_only'
Potential Performance issue; test needed
* On album notification (for a group), sends one distinct email for each user
with a new authentication key.
* When someone clicks the link with auth=<key> in URL, if the user is not
already connected, Piwigo will automatically connect the user.
* new table piwigo_image_format (each photo can have 0 to many formats)
* only compatible with synchronization for now. Formats must be in sub-directory pwg_format
* formats are visible on edition page only for now
