v2.9.3

• CSS: minify comma-separated lists for box-shadow, background, background-repeat, background-size, and background-position properties (fixes #322)
• CSS/SVG: remove deprecated Decimals options in favor of Precision
• cmd: remove --decimals options for CSS and SVG minifiers in favor of --precision
• cmd: add --bundle option to explicitly bundle (concatenate/merge) files into one, do not asume from the -o options if it lacks a / at the end that it outputs to a file and thus needs to merge the inputs
• cmd: directory inputs needs --recursive, previously directories would be expanded by defaults (but not their subdirectories). This matches behaviour of the cp command and will be more intuitive.
• cmd: file inputs are copied without considering and recreating its directory path. For example, minify -o out path/to/file would output to out/path/to/file but will now output to out/file. This is the same behaviour as the cp command and will be more intuitive for users.
