sh404SEF, JoomSEF and AceSEF - Part 2

It has gone over a year since I wrote the first comparison table for sh404SEF, JoomSEF and AceSEF components.

One year is a really long time in this age and manythings can be changed from the scratch, like AceSEF 1.5. So I felt myself compelled to update the comparison table for these components according to their latest releases.

Version Info: sh404SEF 2.1.3, JoomSEF 3.7.4, AceSEF 1.5.0
