normalizeFilename assumes matching path separators

[jcrice]

In lib /less/source-map-output.js at line 25:

    if (this._sourceMapBasepath && filename.indexOf(this._sourceMapBasepath) === 0) {

assumes that filename and _sourceMapBasepath are expressed using the same path separators. This may not be the case if sourceMapBasepath is specified through grunt-contrib-less and the Gruntfile is used on both Windows and *n.x. Normalizing this._sourceMapBasepath before the indexOf call would fix the problem.

Workaround: in the grunt-less-contrib options, set the sourceMapBasepath property using require('path').normalize(mySourceMapBasepath).

My env: LESS 1.5.0 called through grunt-contrib-less 0.8.1 running on Win 7 Enterprise SP1 64-bit. All paths specified in Gruntfile.js are written using '/' as a path separator.

that should fix it I hope.
