[Koha-patches] [PATCH] [replaceprevious](bug #3281) change the way to parse item's summary

[Nahuel ANGELINETTI]

This patch is a "rebased" one for 3.0.x.
This change how to calculate the item's summary, and fix the issue when you have repeated fields.
Now every line is repeated, still it have values in repeated fields(see bug report).
