Feature request: options to ouput only converted rules

[GoogleCodeExporter]

Not always do we want to have the whole CSS file converted, as sometimes we 
would just prefer to override the relevant CSS rules (say in the one file).

I propose to have CLI options controlling the output to be generated - for 
example:

--output-mode x, where x can be:

1: all rules, the default, and current behavior.
2: only the rules that have been converted (RTLfied).
3: the rules that have been converted, and the rules that have been considered 
but not converted. We can have tow sections with a comment header for each.
4: only the rules that were considered but not converted - just for completion.

The rules that have been considered but not converted are the ones where the 
algorithm decides are directional but should not be converted to RTL - examples 
are given in your video demo. These are good to have in order to give a human 
developer the last say.

The above CLI style is just an example, any CLI style that achieves the above 
outcome would do.
