This fix required sorting all of the LIB_PART draw items to ensure
accurate comparison between the symbols stored in the schematic and the
original library symbols. This has a noticeable impact on symbol library
load performance. It may also cause significant changes the next time
the library is saved due to changes in the draw item sorting. Hashing
may be a better solution here but this addressed the immediate problem.
A skeleton method SCH_SCREEN::SwapSymbolLinks() was added because there
is most likely an issue with orphaned symbols in the schematic library
symbol cache during undo/redo operations. More testing is required to
verify this.

cacheLib() can cause a re-load event, which requires the C-locale.
LOCALE_IO needs to be set before this event to prevent mistaken ','/'.'

In particular, there was a typo that kept library values from being
updated, and there was missing logic to fetch the various field names
from the library parts (and the change-to part).
Also implements some performance gains by desisting from copying
LIB_FIELDs around every time we want to look at them.

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.
