Lists without separating new lines are not properly converted

[ascheman]

While using the JetBrains AsciiDoctor plugin of @ahus1 I ran into the following problems when converting from MarkDown to AsciiDoc.

Lists without a newline up front are not converted properly to AsciiDoc:

• A preceding new line must be inserted to make it an AsciiDoc list.
• List markers (-) are not converted (to *), this is perhaps a follow up error of not recognizing the list at all?
• Indentation is not followed (all nested lists are set to level 1 lists, i.e., no respective number of *) is used, perhaps also a follow up error.

When converting the following list

# unordered list without separator before first line

This is my typical list without any empty line for separation
- first item
- second item
- third item

I expect the following result:

= unordered list without separator before first line

This is my typical list without any empty line for separation

* first item
* second item
* third item

However, due to #127 I cannot even create a red test case.
