Bernardo Gonzalez Kriegel 05d4c0e69b Bug 12194: Add option 'Oblique title' in labels 
This patch adds a checkbox on Label creator
to use or not an oblique variant of main font
for title

Also fix font selection for title in case an
oblique variant is used.

To test:
Before patch
1) Go to Tools > Label creator
2) Create a new layout, default values but select
any 'Oblique' variant for main font and
'Biblio/Barcode' for layout type
3) Go to Manage batches, create a batch, add items,
export PDF, download
4) Check logs, you must find a line with
'ERROR in koha-conf.xml -- missing <font type="COO">'
for example if main font Courier-Oblique

5) Open PDF, title could be right but not using selected font

After patch
6) Apply the patch
7) Run updatedatabase.pl
8) Repeat 1-2, note new checkbox 'Oblique title',
default checked
9) Repeat export, no new warnings on log
10) Create a new layout or edit an existent one,
uncheck 'Oblique title', save, export again
Check PDF has non slanted title

Followed test plan, works as expected. (See comment #11).

=head1 NAME
labels/label-create-pdf.pl - A script for creating a pdf export of labels and label batches in Koha
=head1 ABSTRACT
This script provides the means of producing a pdf of labels for items either individually, in groups, or in batches from within Koha.
=head1 USAGE
This script is intended to be called as a cgi script although it could be easily modified to accept command line parameters. The script accepts four single
parameters and two "multiple" parameters as follows:
C<batch_id> A single valid batch id to export.
C<template_id> A single valid template id to be applied to the current export. This parameter is manditory.
C<layout_id> A single valid layout id to be applied to the current export. This parameter is manditory.
C<start_label> The number of the label on which to begin the export. This parameter is optional.
C<lable_ids> A single valid label id to export. Multiple label ids may be submitted to export multiple labels.
C<item_numbers> A single valid item number to export. Multiple item numbers may be submitted to export multiple items.
B<NOTE:> One of the C<batch_id>, C<label_ids>, or C<item_number> parameters is manditory. However, do not pass a combination of them or bad things might result.
example:
http://staff-client.kohadev.org/cgi-bin/koha/labels/label-create-pdf.pl?batch_id=1&template_id=1&layout_id=5&start_label=1
