Greasy Fork镜像

Now multiple units can be converted in one line
Added ounces → gram conversion
Now multi-column tables do not shock the script
Added CheckAllRows parameter

Added http://www.amazon.*/*/dp/* addresses to include, now script ingnores table names and tries to find units in any 2-columns table

Now it turns on only on product pages

fixed forgotten debug

It can now convert only one unit per one line, cause multiple convertions per one line don't really work yet. I fix it soon!
