Code Inspection: Properties may be safely replaced with a shorthand

If a CSS ruleset contains a complete set of longhand properties then this inspection suggests transforming them into a shorthand form.

For example, 4 properties: padding-top, padding-right, padding-bottom, and padding-left may be safely replaced with a single padding property.

Note that this inspection doesn't show up if the set of longhand properties is incomplete (e.g. only 3 padding-xxx properties in a ruleset) because switching to a shorthand may change the result. For such cases consider the 'Properties may probably be replaced with a shorthand' inspection.
