Fix common misspellings

Fix common misspellings

Wikipedia's list of common misspellings [1] has a machine-readable
version.  This patch fixes those misspellings mentioned in the list
which don't have multiple right variants (as e.g. "accension", which can
be both "accession" and "ascension"), such misspellings are left
untouched.  The list of changes was manually re-checked for false
positives.
