[SIGNED-OFF]Bug 12068 - label-create-pdf.pl Add support for RTL language

On top of Bug 8375

If you print a label using arabic/hebrew script,
letters are printed in logical direction, from left
to right, giving a mangled result

This patch will try to fix those cases adding a new
perl dependency, Text::Bidi, and using the automagic
feature if it's log2vis() function to rearrange chars
based on detected text 'direction'

To test:
1. Install Text::Bidi package
(apt-get install libtext-bidi-perl)

2. Try a batch, using Helvetica, with a mix of
ltr and rtl (arabic/hebrew) titles, chars are good,
but direction is bad

NOTE: I suggest changing the mapping for 'HO' font
on koha-conf.xml, from DejaVuSans-Oblique.ttf to
DejaVuSans.ttf to view 'title' chars

3. Apply the patch

4. Try again, now the result is good

Formerly a followup of Bug 8375, look sample pics
on that Bug.
Rebased following changes on Bug 8375

Note: Arabic titles will not be displayed, because
current code selects Oblique variant (unless you
change mapping as suggested on 2. )
Hebrew looks good.

Rebased and move use of new dependency to Labels.pm

Rebased on master

this patch works as described : 

the fonts in koha-conf.xml are modified as the following 
    <font type="H"  >/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf</font>
    <font type="HO" >/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf</font>

 Hlvetica oblique is mapped to the same file as helvetica

I used a layout with "Helvetica" font 
and with right justification, 7 font size
I tested it with an Arabic items
the results exported is very good for me as an Arabic reader 

Thank you Bernardo .
