richedit: Removed some unused invalidation code (try 2)

[Dylan Smith]

(updated the patch so it applies to current code)

The ME_InvalidateFromOfs and ME_QueueInvalidateFromCursor functions are
never called, and the nInvalidOfs variable had its value set but never
used.

ME_InvalidateFromOfs just invalidates the end of the line starting at a
character identified by nCharOfs. ME_QueueInvalidateFromCursor stores
the offset of the cursor in nInvalidateOfs which is never used.  I
checked the commit they came from and saw that they were used to queue
the invalidation when delete or backspace key was pressed, and then the
end of the row at the cursor would be invalidated at the end of
ME_WrapMarkedParagraphs.

Currently invalidation is done by marking paragraphs with the
MEPF_REWRAP flag for content changes, and MEPF_REPAINT when the
paragraph just needs painting.  This also handles following rows on the
paragraph that need updating when the delete or backspace keys are
pressed.

Therefore this patch removes the unused code and variables.
