Autocontinue also applied to singe line comments outside of the docs

[fprott]

For some reason the Autocontinue feature will automatically insert new comments even when outside of a doc-string and/or multi-line comment.
In other words, this // will be inserted if I make a new line after any // regardless if it is useful or not.
This is not useful for two reasons:

1. The user does not expect this behavior outside of the doc-strings from this package
2. It breaks the idea for using multi-line comments

It would be useful to turn this feature off or enable the option to turn it off.
