- added prefix setting: you can choose your own compressed file prefix, if left empty it will overwrite the file which is compressed.
- files are synchronised after compression
- fixed plugin name typo (squeezer instead of sqeezer). You'll probably need to unninstall old one and install new one, not sure how this goes.
if file is overwritten there's no undo possibility (I am looking for a way to create UNDO action, if anyone can help please do so ;), as I am novice to open API)
