Fix incorrect detection of tool charges vs tool count in crafting requirements.

A negative value indicates a tool count (e.g. 2 hammers), while a positive number indicates charges.
Not all parts of the code did made this check correct, some assumes that the tool count is always 1.
Show message from acid damage even with minor damage.

Currently the message is only shown when the field density is 3, for lower density the damage is applied, but no message is printed.
Print "book is too complex" only once when starting to read.
