Subject: [PATCH] Update Items.cpp

reworking r9343

- the part about Food System is obsolete, already was happening in code prior to r9343

- the flags got removed and a boolean is used instead, allowing a simpler function for the remaining disease

- wether an item is considered exclusive to disease feature or not is decided by usage of tag in items.xml
