Road to 1.9.1

Road to 1.9.1
* templating of normal acquisitions
* some graphic changes (use of yellow color as "acquisition/cataloguin" symbol, header consistency...)
* minor reordering of screens (newbasket.pl now unused)
* few bugfixes

When templating finished, the recieving of a book will be ended by a "calatoguing" screen.
Cataloguing will be MARC cataloguing or non-MARC cataloguing, depending on "acquisitions" system parameter.
