#1386 Literals (null, true and false) missing in json lexer

[Jorge Moraleda]

Consider adding literals (null, as well as booleans true and false) to json lexer per RFC 7159: https://tools.ietf.org/html/rfc7159#section-3

[Zufu Liu]

It's application's response to set keywords to lexers, for JSON lexer, you can call SCI_SETKEYWORDS(0, "null true false") to set these keywords.

see https://www.scintilla.org/ScintillaDoc.html#SCI_SETKEYWORDS

[Jorge Moraleda]

Thank you @zufuliu. I can confirm that indeed adding the keywords as you suggest works. Someone with enough privileges can close this ticket.
