Bug 4283 - Merge bibliographic records

Adds a GUI for deduplicating regions of the biblionumber space in Koha.
Deduplication happens using the given
C4::Matcher. Deduplicated biblionumber slice is limited with LIMIT- and
OFFSET-clauses as well as a starting
biblionumber by C4::Biblio::GetBiblionumberSlice().

Deduplication search has the following defaults: Limit = 500, Offset = 0,
Matcher = the lowest matcher_id in DB.

The speed of the deduplication process is mostly influenced by the complexity
of the Matcher, but the GUI can
handle a limit of ~1000 relatively well with a Matcher using ~7 match points
taking a couple of minutes.

>From the deduplication GUI, merging is done with the lists-based
cataloguing/merge.pl -tool.

-2. Define/choose a Matcher from the admin/matching-rules.pl. For tutorial
purposes use the default ISBN-based
    Matcher.
-1. Add two or more Bibliographic records, each having the same ISBN. Note the
biblionumbers.
 0. Reindex the search index.

-TEST  PLAN:-

1. Go to cataloguing home (cataloguing/addbooks.pl) and observe a new toolbar
item, "Deduplicator"! Go there!
2. In the deduplicator.pl, choose your Matcher and "Deduplicate!". This uses
the default values.
2.a. If you don't get any results, enter the smaller biblionumber of the
recently added duplicate ISBN Biblios'
     to the input field. Then retry submission. Use Limit of 2 for convenience.
3. Click the checkbox of a matched result to set it as the "merge
target/reference", then click one or more
   matches to merge with the "merge target/reference", then click the
"Merge!"-button on the boldfaced
   "match source"-row.
4. Merge using the merge.pl-tool as you normally would. As of writing that
merge-feature supports only two
   Biblios, but Buug 8064 will bring support for merging multiple Biblios at
once.

UNIT TESTS included for the C4::Biblio::GetBiblionumberSlice()
