This change is the same as the one that introduced the options to
img2webp:
0825faa4 img2webp: add -sharp_yuv/-near_lossless
Change-Id: Id380d159299c38dd6440f833d487e00c0976afec
this makes the output from img2webp and the ordering in doc/tools.md and
man/img2webp.1 consistent
Change-Id: Ic389aaa29c20128f2b87f231be383094602f125b
Both are global settings. Modifying them at the frame level is left as a
follow up based on need.

Break the main README into into multiple pages in the doc/ directory,
except for the tests, swig and webp_js docs which are in the corresponding
directories.
The webp mux doc is merged into the API doc and the tools doc.
