!!!Changes proposed for Creole 0.4

There is a lot of changes proposed for Creole 0.4, and some of them are interdependent. I will try and list them here, so that we can have a better picture. If I skip something, feel free to add it.

* treat "\n" in paragraphs as space, not as forced line breaks (ChangeLinebreakMarkupProposal);
* have a "forced line break" markup (which one? [Talk.Linebreaks]);
* start headings with single "=", not double ([Talk.Headings]);
* allow "}" at the end of nowiki and preformatted blocks ([Talk.PreformattedAndNowiki]);
* allow forced line break in table cells;
* require whitespace after a bullet in lists (RequireSpaceAfterBulletProposal);

Changes still discussed that seem too immature for 0.4, probably to be proposed for 0.5:

* quoting markup;
* table headings;
* multiline list items;
* indented block markup;
* escape character;

That's just my "impression" of where we stand, but I think it's important to know it. Now, do we just put it into a draft and discuss it as a whole? This version seems to bring a lot of pretty important changes.

Edit: Updated the list according to comments in [Talk.News_blogentry_070107_1], added links to porposals and discussions.
