Bug 28066: Remove select tag's size attribute where it is 1

Bug 28066: Remove select tag's size attribute where it is 1

This patch removes the "size" attribute from <select> tags where the
value of the attribute is 1. The attribute is unnecessary because the
default value when the attribute is undefined is 1.

This will allow for more careful sizing of <select> tags without a size
attribute while preserving the desired behavior of <select> tags which
have a size greater than 1.

The patch modifies 83 files but makes the same minor corrections to
each. I think examining the diff is sufficent, or testing a
representative set of pages:

 - Administration -> MARC frameworks -> MARC structure -> Edit tag:
   The "Authorized value" select.
 - Patrons -> New patron: The "Library" select.
 - Reports -> Patrons with no checkouts: The "Into an
   application" selects.

If anyone would like help testing any particular template I can
follow-up.
