#5 char '\' not excaped when used in itmap

When there are a lot of items, bbe-1.05 uses char '\'
to mark items in itmap, but does not escape it.
...
items["Y"]=cell{item="it-key_c"}
items["Z"]=cell{item="it-whitebomb"}
items["["]=cell{item="it-surprise"}
items["\"]=cell{item="it-pipe-es"}
...
in last line "\" should be escaped i.e. "\\".

It should also be escaped in itmap.
