This function attempted a poor-man's natural compare but it assumed
specific structure of the string. This broke for strings with
numberings that looked like decimals.
Instead, we use our natural string comparison function and remove the
references to this older function and its similar elements.

Duplicates are reannotated on paste in the same way in pcbnew and
eeschema such that when copying and pasting the same block in the
pcb and schematic, the reference designators will match.
wx/wx.h includes all wxWidgets .h files, and sometimes creates collision
names in #define between kicad and windows headers
Moreover, blindly including a lot of useless files is compil time consuming
