Add corrections for all *in->*ing words starting with "J"

In my experience and in my personal projects, a common mistake is to write an
"*ing" word (e.g. jumping) without the final "g" (e.g. jumpin).

Using a quick and dirty script, for every *ing word in the dictionary, there is
now a correction when it is missing a final "g". If the word without a final
"g" appeared in the aspell dictionary, it was excluded.

This changes only contains words starting with the letter
"J" to contain the scope.
