Support passing arbitrary parameters to the SASS compiler about django-sass-processor

[jrief]

My approach to this is to install fonts-awesome and the bootstrap-sass library into a folder node_modules. Then in _variables.scss I add:

// configure the font include pathes
$icon-font-path: unquote(get-setting(NODE_MODULES_URL) + "bootstrap-sass/assets/fonts/bootstrap/");
$fa-font-path: unquote(get-setting(NODE_MODULES_URL) + "font-awesome/fonts");

NODE_MODULES_URL is declared in my settings.py

This a) is DRY and b) doesn't require to pass a bunch of parameters on the command line.

what for?

My sass bin shows the following as possible inputs.

Usage: sass [options] [INPUT] [OUTPUT]

Description:
  Converts SCSS or Sass files to CSS.

Common Options:
    -I, --load-path PATH             Specify a Sass import path.
    -r, --require LIB                Require a Ruby library before running Sass.
        --compass                    Make Compass imports available and load project configuration.
    -t, --style NAME                 Output style. Can be nested (default), compact, compressed, or expanded.
    -?, -h, --help                   Show this help message.
    -v, --version                    Print the Sass version.

Watching and Updating:
        --watch                      Watch files or directories for changes.
                                     The location of the generated CSS can be set using a colon:
                                       sass --watch input.sass:output.css
                                       sass --watch input-dir:output-dir
        --poll                       Check for file changes manually, rather than relying on the OS.
                                     Only meaningful for --watch.
        --update                     Compile files or directories to CSS.
                                     Locations are set like --watch.
    -f, --force                      Recompile every Sass file, even if the CSS file is newer.
                                     Only meaningful for --update.
        --stop-on-error              If a file fails to compile, exit immediately.
                                     Only meaningful for --watch and --update.

Input and Output:
        --scss                       Use the CSS-superset SCSS syntax.
        --sourcemap=TYPE             How to link generated output to the source files.
                                       auto (default): relative paths where possible, file URIs elsewhere
                                       file: always absolute file URIs
                                       inline: include the source text in the sourcemap
                                       none: no sourcemaps
    -s, --stdin                      Read input from standard input instead of an input file.
                                     This is the default if no input file is specified.
    -E, --default-encoding ENCODING  Specify the default encoding for input files.
        --unix-newlines              Use Unix-style newlines in written files.
                                     Always true on Unix.
    -g, --debug-info                 Emit output that can be used by the FireSass Firebug plugin.
    -l, --line-numbers               Emit comments in the generated CSS indicating the corresponding source line.
        --line-comments

Miscellaneous:
    -i, --interactive                Run an interactive SassScript shell.
    -c, --check                      Just check syntax, don't evaluate.
        --precision NUMBER_OF_DIGITS How many digits of precision to use when outputting decimal numbers.
                                     Defaults to 5.
        --cache-location PATH        The path to save parsed Sass files. Defaults to .sass-cache.
    -C, --no-cache                   Don't cache parsed Sass files.
        --trace                      Show a full Ruby stack trace on error.
    -q, --quiet                      Silence warnings and status messages during compilation.

In many cases I would like to be able to pass -r

-r, --require LIB                Require a Ruby library before running Sass.

Which makes it easier to include SASS code from ruby gems (like when using font awesome icons).

--compass is also nice, as it includes all the compass stuff.
