Use local static variable for ArtID mapping table

Browse Source 
The instantiation of the global static mapping table may happen before
the instantiation of the wxArtIds, i.e. the copy-constructor would
access not yet valid wxArtId/wxString instances.

Delay the instantiation until the first call to wxArtIDToStock call.
This is still not 100% safe, as wxArtIDToStock may be called by a
constructor of a static instance, but hopefully nobody does that.
