Readme enhancements about sublime-better-coffeescript

[lavrton]

I think we don't need special branch or package for ST2. Master branch now support both of ST2 and ST3. New features and bug fixes should be tested on each version. When ST3 will be available for free using we will remove "ST2 code".

There must be something about st3 api that wouldn't be compatible with st2, is there not?

Let's just keep it anyway for now. Maybe something will cause a problem, then we can fix it just for st2 or st3. Otherwise only readme would be different and we would patch st2 up with the changes made for st3.

Yes, st3 api can be different with st2 api. But it happens very seldom.
We can write something like to solve this problem:

if python_version == 2:
    sublime.api2()
else:
    sublime.api3()

I think it will be easy to maintain and use plugin. Right now everything works for both versions for me.

Sounds good to me! I've just started using st3 today. What seems to be the best feature you have seen so far? From a users point of view and developers.

Use https://github.com/aponxi/grunt-readme-generator to generate the readme... Oh goodie!

Going to close this... we will have to re-write readme anyways... for 2.0
