Add markdown extention to the README

[KonradIT]

The readme file has some markdown syntax, for instance the - character one line blow the headings, and the * to make a list. I added .md to readme, now is readme.md and it looks great. See: https://github.com/KonradIT/FFmpeg/blob/master/README.md

From IRC:
llogan: might be kind of weird to have one be markdown style and the others not
llogan: INSTALL, etc

[KonradIT]

Shall I add .md to the other files? Or close PR and issue?

Hi. Thanks for the contribution. If you markup and rename the other files referenced in README (LICENSE and INSTALL), then I'll be happy to merge it.

Ok, so I added the missing .md extentions and added more markdown syntax for titles, lists, headings... New commits are:

Line 6 fixed by 2fb3ef0

OK, now? https://github.com/KonradIT/FFmpeg/blob/master/INSTALL.md

What about using blah instead of blah? There should be a blank line above 2. and above 3. in INSTALL.md. That should be all of the requested changes.
