Draft-js: `splitTextIntoTextBlocks` should adhere to Unicode standard

[eelco]

When pasting text with line-separators (U+2028), it’s not split.

Example (copy from here):

aap
noot
mies

Expected when pasting

aap
noot
mies

Unicode line breaking algorithm: http://www.unicode.org/reports/tr14/tr14-32.html#Algorithm

Suggested fix:
Change NEWLINE_REGEX to

var NEWLINE_REGEX = /\r\n?|\n|\u000C|\u000B|\u0085|\u2028|\u2029/g;

Thanks for reporting this! Seems reasonable to me, I'd like to look at our uses and see if there is any reason it was not done in the first place. I'm guessing it was just an oversight though.
