Adds a possibility to replace properties inherited from base types with
a more specific ones. For example, such properties may have:
- different meaning which should be reflected in property name
(e.g. TRACK::{G,S}etWidth() sets actual track width, but
VIA::{G,S}etWidth() modifies the diameter)
- different set of possible values (e.g. BOARD_CONNECTED_ITEM::SetLayer()
should accept any copper layer, but MODULE::SetLayer() works only with
F.Cu and B.Cu)
Introduces classes:
- INSPECTED: base class for types taking advantage of
generic properties system.
- PROPERTY*: meta-data storing information about properties
- PROPERTY_MANAGER: singleton class to get properties data
