Revision 578311

PropertyCache phase 2:
        * improvement of the PropertyCache itself should guarantee acceptable
          performance of the static caches in multi-session environments, which is 
          a possible problem with synchronizedMap
        * changed CommonFont to use the cache: 
          added CachedCommonFont to contain the properties that are always cacheable
          CommonFont itself is only cached if the remaining properties are absolutes
        * changed CommonHyphenation, KeepProperty, ColorProperty and FontFamilyProperty
          to use the cache

Facilitate the implementation for font-selection-strategy:
        * Changed FontInfo.fontLookup to always return an array of FontTriplet
        * Changed CommonFont.getFontState to return an array of FontTriplet
        * Initial modifications to the related LMs: initialized with
          the font corresponding to the first of the triplets
