Cameron McCormack eb09a50905 Bug 649142 - Part 1: Add macros and flags for defining logical properties and don't allocate storage for them in nsRuleData. r=dbaron
We define a new flag CSS_PROPERTY_LOGICAL to be used for logical longhand
properties and a new CSS_PROP_LOGICAL macro in nsCSSPropList.h to
define them.

When using CSS_PROP to capture all properties, includers must now
explicitly indicate whether logical properties are included or not,
by defining CSS_PROP_LIST_EXCLUDE_LOGICAL (to exclude them),
CSS_PROP_LIST_INCLUDE_LOGICAL (to include them), or CSS_PROP_LOGICAL
(to capture them separately from other properties).
