Node v0.10.0

Response to Issue 65

Changed the default file name for generated CSS files from nodesass.css
to <originalfilename-without-scss>.css.

Now it should be possible to use globbing and get all generated files in
ones current working directory:

./path/to/node-sass path/to/styles/*.scss

generates all CSS files named like their SCSS counterparts.

Canon libsass

Use a wrapper to store the callback info and the context, this way we
can use the unmodified libsass

Convert the options to camelCase. Fixes #43

Still supporting the old style though

Pull request looks okay.  I'm merging it in.

re #61 proper linux x64 binaries

Just a simple bugfix at npm install line in readme file

Updates to CLI / bin utility for node-sass

add a command line binary interface for node-sass

update libsass

node-sass sass.scss output.css

Where sass.scss is the Sass file to compilte, and output.css is the filename to output.

Added fs.writeFile functionality to the node-sass bin, so that output if read in and compiled correct are then output to the filesystem based on the given arguments. Default output file is "nodesass.scss"

Did not add additional tests for this, lame.

a simplification of the default options setting
