CHANGED: All mandatory fields in derived symbols can be edited. This
not only includes the field value but also all text properties.
Kill the dual datasheet variable storage which caused many datasheet
bugs over the years. The datasheet is now always stored in the data
sheet field.
It looks good, but non-mandatory fields have an ID of -1, so it
doesn't actually work. Some places got around this by converting
the ID to unsigned, but this just hides the real issue from
unsuspecting coders.

Add also a comment in common.cpp about using wxLocale instead of setlocale.
DIALOG_UPDATE_FIELDS has issues in non English languages, due to its design.
The fix for mandatory fields is only a partial fix that avoid major issues.
This change completely removes the LIB_ALIAS design pattern an replaces
it by allowing LIB_PART objects to inherit from other LIB_PART objects.
The initial implementation only allows for single inheritance and only
supports the mandatory fields in the derived part because that is all
that the current symbol library file format will support. Once the new
file format is implemented and saving to the old file format is deprecated,
more complex inheritance will be added. The LIB_ALIAS information saved
in the document files was move into the LIB_PART object. This change
impacts virtually every part of the schematic and symbol library editor
code so this commit message is woefully incomplete.
REMOVE: Removed the symbol aliases concept from the schematic and symbol
editors and the symbol viewer.
NEW: Replace the symbol alias concept with simple inheritance that allows
a library symbol to be derived from another library symbol.
