Contribute db renderer

Hello,
I called this renderer "db" renderer since i use it to display and update json data of a mongo db.
If you decide to include it into jsonary I would also provide a test case, so that we can assure it functions when new releases come out…
The main features are:
- it allows  the use of displayOrder (non-standard) attribute in JSON schema to assure that attributes of an object are always displayed in the same order
- it allows the use of displayAsTable (non-standard) attribute to display the attributes of an object horizontal instead of vertical ("as a table") 
- it uses the title attribute instead of the name attribute if available
- some more info added to html for better css
