suggestion to no use the sourceMapFileInline option

When searching for a solution for gulp-community#126 i wondered why using Less with sourceMapFileInline (setting the SourceContent property of the source map with source files contents).

Not using the sourceMapFileInline and using `result.map` directly gives me the same results after some testing.
