Improve appearance of export file path

I fixed two issues
1. We were using two kinds of numerals in the file path, arabic
   and english. Lets just stick with english numerals
2. English numerals are "weakly LTR" characters. Therefore,
   having the following formatting 0001.vcf is equivalent to
   <weak ltr chars><neutral chars><strong rtl chars>. This results
   in weird rendering, since the default locale is RTL. Fix: put
   the url in a LTR embedding.
