docfix for today's release

Complete textwrap.wrap() with 6 missing params! (#207)

Make available all keyword parameters for ``wcwidth.wrap()`` as ``textwrap.wrap()``.

New Parameters expand_tabs, replace_whitespace, fix_sentence_endings, drop_whitespace, max_lines, and placeholder for wrap(), completing stdlib textwrap.wrap() compatibility.

rephrase ucs-detect for upcoming version

Standalone emoji support (#202)

CLoses #133 and #154.

This decreases general performance by ~10% for complex CJK/combining and emoji strings.

- Regional Indicator pairs measured as one 2-cell flag; unpaired RI measured individually
- Fitzpatrick skin tone modifiers are zero-width when following an emoji base, Narrow when "standalone"

Bugfix zero and wide tables were not trimmed (#196)

- Bugfix that the zero and wide tables were not actually trimmed in 0.5.0 release, pie on my face!
- also, add test coverage of ``_parse_sgr_params`` special SGR modes parsed

some tiny punctuation fixes

New functions: iter_graphemes_reverse(), grapheme_boundary_before() (#…

…192)

As I audit and integrate with dependent libraries, in [urwid](https://github.com/urwid/urwid/) I find the need to help "move the cursor left" and look backwards from a location in a string to the previous boundary, while looking forward using ``iter_graphemes()``.

Looking backwards is provided by new function ``grapheme_boundary_before()``.

The more obvious function, ``iter_graphemes_reverse()`` is provided (though not useful to urwid). @penguinolog

release 0.3.5 for failing test

prepare for 0.3.4
