Subject: improvement: upgrades id retrieving in include/common.inc.php and
 upgrade_feed.php are now made by dedicated function
 get_available_upgrade_ids.

bug fixed: after an installation, you had to play all available upgrades,
which was wrong. install.php inserts informations related to all available
upgrades at installation time. Thus avoiding automatic upgrades.
