Adblock Plus and (a little) more: Small improvements

A new Adblock Plus 0.7.5.5+ development build (2008062401) has been uploaded. Only en-US locale is available at the moment.

Added new filter composer dialog that is opened to add a new filter
Added hidden preference extensions.adblockplus.usefiltercomposer to choose between filter composer and preferences dialog for adding of new filters (this preference might be removed later)
Moved warning that Adblock Plus is disabled from preferences to composer dialog, made it possible to enable with a single click
Blockable items: Changed default action for blocked items to “add exception rule” instead of “edit filter”
Blockable items: Tooltip now shows the filter subscription name in addition to the filter
Blockable items: Added “Copy filter” item to the context menu
Blockable items: Multiple selection and copying of multiple addresses/filters now possible
Blockable items: Added “Select all” item to the context menu
Fixed: Subscriptions are sometimes loaded from browser cache
Added hidden preference extensions.adblockplus.savestats to allow turning off hit statistics (useful if patterns.ini is put into a version control system)
Firefox 1.5, Thunderbird 1.5 and SeaMonkey 1.0 are no longer supported
Flock 1.2 is supported now
Cleaned up some backwards compatibility hacks
Removed ancient drag&drop handling code (not discoverable and not advertised anywhere)
Fixed: Dates in Preferences window would sometimes use wrong character encoding (bug 441370)
Preferences: Pasting filters that contain spaces (especially comments) now possible (bug 18920)
