Comparable/Comparator implementation now use fast Java built-ins for
primitive types rather than hand-coded versions. Also DRY some code
and simplify logic.
This maintains the "biggest stack first" notion of "ascending", but
also fixes the inconsistent/accidental reversal of sort by mod (the
mod name should sort the same direction as the item name).
This is first update pass, which is mainly import reorganization, name
fixes, etc... Although some parts of second were done where changes
aren't important.
Errors: ~1400 -> 82.
Reduces the visibility of all fields to private and create setters/getters
when necessary. Exceptions are fields with GuiSync as these need to be
public.
Reduces the visibility of internal methods to private/protected/default when possible.
