Added Guardfile support for the wonderful Guard by @thibaudgg

I've found that if you aren't specifically working on a ruby file this script likes to set the syntax of say a python file to Ruby i modified the script a lil bit to prevent this thanks for the script!!!!

Btw it seems it specifically has to do with the Gemfile line heres the modified script.

Good fix, the RSpec stuff was breaking anyway, took it out. Added your line for gemfile with an additional one for guardfile

I've updated this script to work with https://github.com/n00ge/sublime-text-haml-sass

For some reason Sass files were incorrectly detected as Ruby Haml.

where does this go?

Please note that you should probably be using the DetectSyntax package from Package Control instead of this outdated hack.

Hi,

My .sass files were being detected as Ruby Haml syntax. I found your script and tried by using DetectSyntax on ST2.
Unfortunately its still failing on detection. I tried to add a Sass rule in the user configurations for the plugin but it doesn't seem to work also.

(...)
{
    "name": "Sass",
    "rules": [
        {"file_name": ".*\\.sass$"}
    ]
}
(...)

Do you have anything to share?
