🐞 Code highlights incorrectly disabled on files with extension name '.c++'

[NathanShi]

Description

Code highlights incorrectly disabled for c plus plus source code file with extension name '.c++' by default. Here's a screenshot that showed this:

As you can see above, these two files with exactly same code, but highlights works on '.cpp' file, not work on '.c++' file.
It seems that CodeEdit won't recognize the '.c++' file as a c plus plus source code automatically.
Workaround: Set the type of '.c++' file to 'Cpp' on inspector for every '.c++' file manually.

To Reproduce

1. Open a c plus plus file with extension name '.c++'.
2. Done.

Expected Behavior

Highlight the codes for '.c++' files, just like what CodeEdit do to '.cpp' file.
