Bug 18076: Replace holds_to_place_count with an input type=text

Bug 18076: Replace holds_to_place_count with an input type=text

From http://www.template-toolkit.org/docs/manual/Directives.html#section_WHILE

"""
The Template Toolkit uses a failsafe counter to prevent runaway WHILE loops which
 would otherwise never terminate. If the loop exceeds 1000 iterations then an undef
exception will be thrown, reporting the error:

WHILE loop terminated (> 1000 iterations)

The $Template::Directive::WHILE_MAX variable controls this behaviour and can be set
to a higher value if necessary.
"""

I do not think we want to increase this value, and I do not think we want to display a
dropdown list with 1000 entries.

This patch replaces the dropdown list with an input text.

Test plan:
- Set circulation conditions - holds per record = 999
- Search for record with items
- Go to the holds tab
- Search for a patron
- Verify that when you send your search, the 'internal server error' is not shown
and you see the input text.
You should be able to enter a value > than 999 and < 1
