Don't highlight things that don't exist, add some missing keywords,
highlight true/false/nil as constants instead of keywords, and
highlight types as types instead of constants.
- move type cast keywords into operators, since that's their syntactic function
- fix a single dot being matched as a constant.number
- add the missing caret operator
* Overall syntax highlighting improvements for C++
Most of these changes are based on the information on cppreference.com;
specifically from here: https://en.cppreference.com/w/cpp/keyword
- made `identifier` actually match any identifier
- add ~ as an operator
- add `static_assert` as a keyword (statement)
- add keywords that are interchangeable with operators as operators
- add keywords `sizeof`, `alignof` and `typeid` as operators
- add the quasi-keywords `asm`, `fortran` and `final`, `override`
- add the keyword `nullptr`
- add `_Pragma` as a preprocessor keyword
- add C++20 (concepts and modules) -related keywords
- add casting keywords
- add the keyword (specifier) `noexcept`
- remove `nothrow` (because it's not any more special than `vector` is)
- add `wchar_t` and `charXX_t` types
- add cv type keywords as `type.keyword`s
- move some fitting keywords into `type.keywords`
(mostly because they appear in/near type signatures etc.)
I didn't include coroutine-related language features,
primarily because there is no good source of information
about them other than the ISO C++ standard.
* Further changes to C++ syntax highlighting
- reverted the changes to the `identifier` regex, since most
colorschemes color it the same as `type`s and/or `statement`s
- fix the 2nd `type` regex (the word boundaries were in only two pipe-options)
- move `nullptr` back into `constant.bool`,
since it looks better in-editor this way (imo)
- add `?` as an operator
- add regexes that match all the correct number literals, and nothing else

(that is, if I haven't made a mistake)
* Python3: Add built-in object 'cls'
* Python3: Add the bitwise negation operator ~
* Python3: Add support for hexadeximal and binary numerical literals
* Python3: Rewrite '(__foo__|__bar__)' as '__(foo|bar)__', add known '__i.*__' methods
* Python3: Add __iter__ as a magic method, sort the list of magic methods
* Python3: Numerical literals: Add support for '_', disallow leading 0 for decimals
* fixup! Python3: Numerical literals: Add support for '_', disallow leading 0 for decimals
hex oct and bin have different sets of allowed digits
* Python3: Add support for floating point numbers with optional scientific notation
* Python3: stop single-line strings at EOL
* Python3: Add support for TODO and FIXME in comments
* Python3: Add support for the ^ bitwise xor operator
* Update coffeescript.yaml
We need much much more modern coffeescript standards, the current one has broken `0x123456` (hex) and single quotes, and doesn't support multiline comments. This PR aims to fix that. I'm no regexp expert, I just based this off JS', so tell me if I did anything wrong.
* Update coffeescript.yaml
The python3 syntax had "filename" instead of "filetype"
as the header. This commit also makes standard py extensions
use the python3 highlighting and requires .py2 or a python2
env to use python2 highlighting because python3 is the standard
python now.
Fixes#1592
