Version Update

Hey,
Great plugin for LessPHP, worked great for our coding process without needing to install Java/Phyton/Ruby script to work with this. May I suggests some topics here?

- Added proxy cache bypass (filename.<time>.png)
Great for high caching environments

- Added option to work with wrapped sprites
See Readme.md for more infos

- Added option to add default image padding ( iOS sprite bug )
Using sprite-pad() all time is not a nice solution... 

- Added option to auto-add image dimensions
Reducing coding process

- Added "display: block"
Simplifing the coding process, may need add option to toogle block/inline-block

- 0px trasnlated to "0"
Universal sizing

- Removed auto-generated folder
Really not needed in my opinion
