Paul POULAIN 154e383a1d BUGfixing authorities editor 
With the YUI tabs, the SINGLETAB feature (that hides tabs when there is only 1) was bugguy
This commit fixes the problem, and solve some other ones :
- order the fields
- resize the input size (see previous commit in addbiblio.pl)
- remove some unused code
- reindent

# Revision 1.44 2007/04/05 12:17:55 btoumi

#
# Revision 1.43 2007/03/30 11:59:16 tipaul
# some cleaning (minor, the main one will come later) : removing some unused subs
#
# Revision 1.42 2007/03/29 16:45:53 tipaul
# Code cleaning of Biblio.pm (continued)
#
# All subs have be cleaned :
# - removed useless
# - merged some
# - reordering Biblio.pm completly
# - using only naming conventions
#
# Seems to have broken nothing, but it still has to be heavily tested.
# Note that Biblio.pm is now much more efficient than previously & probably more reliable as well.
#
# Revision 1.41 2007/03/29 13:30:31 tipaul
# Code cleaning :
# == Biblio.pm cleaning (useless) ==
# * some sub declaration dropped
# * removed modbiblio sub
# * removed moditem sub
# * removed newitems. It was used only in finishrecieve. Replaced by a TransformKohaToMarc+AddItem, that is better.
# * removed MARCkoha2marcItem
# * removed MARCdelsubfield declaration
# * removed MARCkoha2marcBiblio
#
# == Biblio.pm cleaning (naming conventions) ==
# * MARCgettagslib renamed to GetMarcStructure
# * MARCgetitems renamed to GetMarcItem
# * MARCfind_frameworkcode renamed to GetFrameworkCode
# * MARCmarc2koha renamed to TransformMarcToKoha
# * MARChtml2marc renamed to TransformHtmlToMarc
# * MARChtml2xml renamed to TranformeHtmlToXml
# * zebraop renamed to ModZebra
#
# == MARC=OFF ==
# * removing MARC=OFF related scripts (in cataloguing directory)
# * removed checkitems (function related to MARC=off feature, that is completly broken in head. If someone want to reintroduce it, hard work coming...)
# * removed getitemsbybiblioitem (used only by MARC=OFF scripts, that is removed as well)
