Bug 8375 - Followup - Use unicode bidi for rtl languages

If you print a label using arabic/hebrew script,
letters are printed in logical direction, from left
to right, giving a mangled result (see LTR-bag.png)

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

3. Apply the patch

4. Try again, now the result is good
(see LTR-good.png)
