WIP: BUGFIX: Rework to include shared text in shared links

[harshad1]

This addresses the issue brought up in #2281

We will now have the link text properly included in the link.

Lines in shared text will be formatted as links iff

1. They are a file path
2. They end with a web link. In this case the part before the web link will be used as the link text

Thank you, seems to be working good enough as first hotfix. (can be further improved of course if needed).

One thing I found especially different nowadays is that the todo.txt treatment is gone now. Previously a new task with creationDate was added. Now it's just text added without date.

We check the file format and add the date if it is a todo.txt file:

https://github.com/gsantner/markor/blob/master/app/src/main/java/net/gsantner/markor/activity/DocumentShareIntoFragment.java#L343-L347

            if (format == FormatRegistry.FORMAT_TODOTXT) {
                formatted = TodoTxtTask.getToday() + " " + formatted.replaceAll("\\n+", " ");
            } else {
                formatted = "\n" + formatted;
            }

So if this is not working for you that is a bug somewhere. If you confirm, I can try to find it.
