Wayne Stambaugh 8ff51d8899 Eeschema: add schematic sheet page number. 
The groundwork has now been laid for per sheet instance data.  Initially
this only supports sheet page numbers but could be expanded to include
other per sheet instance information.

ADDED: Support for user defined schematic page numbers.
