Cleanup: Grammar: Fix uses of "for e.g."

e.g. stands for "exempli gratia" in Latin which means "for example".
The best way to make sure it makes sense when writing is to just expand
it to "for example". In these cases where the text was "for e.g.", that
leaves us with "for for example" which makes no sense. This commit fixes
all 110 cases, mostly just just replacing the words with "for example",
but also restructuring the text a bit more in a few cases, mostly by
moving "e.g." to the beginning of a list in parentheses.
