Rust Enhanced package breaks AutoSetSyntax package

[BlackDex]

Sublime Text Version

Sublime Text 3 (Build 3211)

Rust Enhanced Version

v2.21.0

Operating system

A good example is:
OS Name Arch Linux
Version All updates installed

Expected behavior

Should not break AutoSetSyntax package.

Actual behavior

Breaks AutoSetSyntax extension.

Steps to reproduce

1. Install both Rust Enhanced and AutoSetSyntax package.
2. Check the debug console ctrl+`
3. AutoSetSyntax reports errors.

The issue is that in Cargo.sublime-syntax the setting file_extensions is just a string.
But according to Sublimetext it needs to be a list of strings. https://www.sublimetext.com/docs/3/syntax.html

When i change it from just rs to ['rs'] all starts working again.

@BlackDex I just came across this myself, and have submitted a PR with your fix. Thanks for finding that! Out of curiosity, how did you work out that was the issue? I'm glad I didn't have to dig any deeper after, by process of elimination, determining that this package was the problem, then checking for a GitHub issue here.

@ZimbiX Well it wasn't that hard.
In the ST3 Console i noticed AutoSetSyntax produced an error, and it gave the location where in the python file. So i modified AutoSetStyntax to print the objects in the while loop there, and all printed fine without errors until it came to this package for loading the extensions its providing.

And i noticed it did this on the file_extensions, looked at ST site on how you need to define it, and it should always be an array. So changed that, and all worked out.

@BlackDex Nice. Cheers for the info. I'll keep that in mind for next time
