extension of style parameters

I added the possibility to modify more style properties like
background-color background-image border shadow and text color.

To use it you just have to enter:
1)text color   white
color:#fff

2)background-color   white
bgcolor:#fff

3)background image for example :images:test.jpg
bg:images:test.jpg

4) red border
border:#f00

5) black shadow
shadow:#000
