doc/resampler, swresample/options: use proper capitalization Proper names should be capitalized in all user facing API as far as possible. The option names themselves have not been changed since: 1. We consistently keep option names in lower case. 2. Changing them would break existing scripts. 3. I suspect that we want to be similar to Sox and its relevant options.

swresample: allow double precision beta value for the Kaiser window Kaiser windows inherently don't require beta to be an integer. This was an arbitrary restriction. Moreover, soxr does not require it, and in fact often estimates beta to a non-integral value. Thus, this patch allows greater flexibility for swresample clients. Micro version is updated.
