Bug 12127: fix incorrect DataTable types in Holds to Pull list

Bug 12127: fix incorrect DataTable types in Holds to Pull list

This patch explicitly sets the sType in the Holds to Pull list table
for the libraries, itypes, and locations columns. It appears that the
type is automatically being set to "html" when it should be set to
"string".

It needs to have a sType of "string", since DataTables will strip out
the <br> tags when using "html", and we need them for the regexp
we use to create a more precise filter search.

_TEST PLAN_

Before applying:

1) Place a "next available" hold on a record with an item available
from one library/branch (e.g. "Branch A")
2) Place a "next available" hold on a record with an item available
from two different libraries/branches
3) Place a "next available" hold on a record with an item available
from three different libraries/branches - one of which is the same
as the library/branch from Step 1.
4) Go to the Holds to Pull List
5) Filter the branches by "Branch A".
6) You should only see the hold from Step 1 - not Step 3.
7) Try filtering on a branch for a hold that has multiple
libraries/branches. (They shouldn't appear when filtering, except
when using the "None" filter).

Apply the patch.

After applying:
1) Repeat Steps 4-7 from above. When filtering on "Branch A", you
should be able to see all holds that are available at "Branch A",
even if they are available at other branches (i.e. the holds has
multiple libraries listed).
