new stable tag 1.5.2

Changed the way the plugin adapts to Fluid layouts, it detect the width through javascript instead of some "hackish" css (the css was commented for future references)
 
 This bug was due to an update in the Facebook Comment Plugin in march/2014
 
 Also there was some  changes made in the admin interface, now the user can choose between Fluid, Fixed or Mobile versions, this as also to remove some ambiguity from the previous admin, which was causing the users to input width and choose mobile version, what was bugging some layouts.
 
 The default layout are also now fluid.
