232b2ccbc4 Move the rest of py23 module to textTools 
Change all imports to use textTools module, except the test_py23.py test
which is kept until we decide to remove the module (if ever).

unicodedata: add ot_tag_to_script function

unicodedata: add script_horizontal_direction function 
same as harfbuzz hb_script_get_horizontal_direction.

We just hard-code the set of RTL script here, as it doesn't change often anyway.
The function is just syntactic sugar as it all does is basically looking up the
constant RTL_SCRIPTS set.
It's nice to have it here in a central place alongside 'script', 'script_name', etc.

unicodedata: add ot_tags_from_script function 
Fixes https://github.com/fonttools/fonttools/issues/1112

This implements the same logic found in harbfuzz hb-ot-tag.cc to
convert between Unicode (or ISO 15924) script codes to OpenType script
tags as defined at:
https://www.microsoft.com/typography/otspec/scripttags.htm

99ea0a3986 [unicodedata] add script_code func and 'default' fallback arg 
`script_code` does the reverse of `script_name`: it takes a long
script name and returns a 4-letter script code.

Both `script_name` and `script_code` raise KeyError by default,
but can optionally return a default value instead.

3442da1529 [unicodedata] use bisect.bisect_right function 
CPython comes with a fast C implementation of bisect module.
This gives 4 to 5 times speed-ups over my pure-python version.

52d6131525 [unicodedata] add new module and 'script' function 
The new `fontTools.unicodedata` module re-exports all the public
functions from the built-in `unicodedata` module, and also adds
additional functions.

The `script` function takes a unicode character and returns the
script name as defined in the UCD "Script.txt" data file.

It's implemented as a simple binary search, plus a memoizing
decorator that caches the results to avoid search the same
character more than once.

The unicodedata2 backport is imported if present, otherwise
the unicodedata built-in is used.
