Changes

Properly merge all and media queries. These queries were previously being merged as though all referred to a specific media type, rather than all media types.
Never remove units from 0 values in compressed mode. This wasn't safe in general, since some properties (such as line-height) interpret 0 as a <number> rather than a <length> which can break CSS transforms. It's better to do this optimization in a dedicated compressor that's aware of CSS property semantics.
Match Ruby Sass's behavior in some edge-cases involving numbers with many significant digits.
Emit escaped tab characters in identifiers as \9 rather than a backslash followed by a literal tab.

The source map generated for a stylesheet read from standard input now uses a data: URL to include that stylesheet's contents in the source map.

this.includePaths for a running importer is now a ;-separated string on Windows, rather than :-separated. This matches Node Sass's behavior.

The URL used in a source map to refer to a stylesheet loaded from an importer is now ImportResult.sourceMapUrl as documented.
