Unification of placement options

All these symbolizers have common purpose - placing labels on geometric positions:

• TextSymbolizer
• ShieldSymbolizer
• GroupSymbolizer
• MarkersSymbolizer
• PointSymbolizer
• CollisionSymbolizer

It makes sense to allow all possible placement options for all these symbolizers. Therefore all these symbolizers now support all these placement options:

• point
• interior
• centroid
• line
• vertex
• vertex-first
• vertex-last
• grid
• alternating-grid

This unification is a result of great code sharing and simple declarative description of each symbolizer.
