C++ not recognized as code-block option

[R1dO]

While fiddling with the rules for the other 'issue', i found out the c++ parameter was not recognized by the lexer.
The reason is that the ++ part is treated as regexp quantifiers instead of characters. It seems those need to be escaped.

On my end this was solved by adapting the code-block-cpp modules in rst.tmLanguage.json:

		"code-block-cpp": {
-			"begin": "^(\\s*)(\\.{2}\\s+code-block::)\\s*(c|cpp|C|C++|CPP|Cpp)\\s*$",
+			"begin": "^(\\s*)(\\.{2}\\s+code-block::)\\s*(c|c\\+\\+|cpp|C|C\\+\\+|CPP|Cpp)\\s*$",
			"while": "^\\1(?=\\s)|^\\s*$",

This adaption includes the lowercase version, since that one was not recognized as well.

I think you should create a pull request for this.
