Fixed List *,*,* and List 1,2,3

Should now fix the conversion to and from numbered <-> bullet list.

## 25) List *,*,*
If the selected text is not a list, then it will be converted to a bullet list using the desired default. If the list is mixed, it will be cleaned up based on the 1 bullet item. *,-,+ will convert to unordered list whereas number will convert to ordered list.

## 26) List 1,2,3
Now handles bullet items correctly by removing them before
prepending numbers to the ordered list.

## Global
- Improved the regex to clean extra lines from bash script.
