FIX:  Python 3x compatibility:
	- changed 'print' to 'print()'
	- added  relative import
	- added 'plugin_loaded' trigger (http://www.sublimetext.com/docs/3/api_reference.html)
	- changed open file method

NOTE:
	- I'm not tested this with non-unicode files
FATAL FIX ERROR

I inadvertently put waste piece of code by copy-n-paste from project. And I have not tested it before commit, sorry. I fixed this.
Update README.md
