Updated command list and "argument-constants" highlighting to CMake version 3.14

[TrinityCoder]

1. Intro

Hello, I am a regular user of Atom Editor together with the language-cmake extension. I have noticed that it has not been updated for a while, which means it's syntax highlighting rules are not up to date with current CMake releases.

I have created this pull request containing updated cmake listfile.cson file, specifically the argument-constants array and the command list above. CMake commit 4aace9b0 was used for extraction (version 3.14).

To extract the argument-constants array, I digged an old Ruby script and made few changes to make it working again: arg_separators.rb.

To extract the list of commands, simple cmake --help-command-list was sufficient.

2. Changes

The command list only has several new commands:

add_link_options
include_guard
target_link_directories
target_link_options

However, the argument-constants array has many new entries:

There are several identifiers that weren't extracted by the arg_separators.rb script and are therefore removed by my commit:

COMP
DFOO
NNNN
VAR2

3. Conclusion

The majority of listed identifiers looks good to me and I think that many of them deserve to be highlighted. I am currently using this version of grammar file with my language-cmake plugin and I enjoy the result; noticeably more words are now highlighted.

I provide this pull request so that you can try it if you want. I would also appreciate comments related to the identifiers which should / should not be added.

I don't use atom anymore, but still, thank for the PR!
