Converts all images in a folder to base64

ImageToBase64.py

'''
   This program converts all images in a folder to base64
   for embedding in an html page inside a <style> tag like:
   <style>
     .img_name1{content:url("data:image/jpg;base64,abcdef...");}
     .img_name2{content:url("data:image/jpg;base64,abcdef...");}
   </style>
   The 'content' property only works in webkit browsers.
