*) Rewrote: 
        PCB_BASE_FRAME::Save_Module_In_Library(): now uses fp-lib-table and PROPERTIES.

        PCB_BASE_FRAME::SelectLibrary(): is now generic for selecting a library, not just the active library.

* Use std::swap for PCB_MODULE_EDGE_T items in SwapData().
* Add assignment operator to EDGE_MODULE object.
* Move code from copy method to assignment operator.
* Minor coding policy fixes.

*) Save library nickname in APP so upon module editor re-entry last is re-used.
*) Fix bug editing fp-lib-table Description field.

Code cleanup: remove m_Son member in EDA_ITEM which was never used.

Show the "Description" field from fp-lib-table in pcbnew's module editor 'set current library' dialog.

Fix a very minor bug (2 duplicate lines when copying version informations to the clipboard)

columns.  DIALOG_SHIM would resize each separate usage to the same
size.  DIALOG_SHIM now supports and alternate m_hash_key in lieu
of the class name, optionally.

Pcbnew: add WIN32_LEAN_AND_MEAN define in github_plugin.cpp. Note: this define is already in use in avhttp build (Windows specific)
