Item lookup search
(#50)
you can now look up items in the items table by fields using operators (< > = <= >=)
example hp>=500
will return items with hp value greater than or equal to 500
you can also multi search to refine
put the searches inside {} separated by a comma
example {hp>=500, hp<1000, strength>20}
this will return items with hp values from 500 - 999 and only with strength values of 20 +
