[logback-dev] Logback appender for MongoDB

[Tomasz Nurkiewicz]

Here is precisely what I created so far:

* base abstract appender handling MongoDB connectivity [1]
* standard appender [2] + tests [3]
* access appender (tested with Tomcat) [4] + tests [5]
* configuration examples [6]

By quick googling I found several other community implementations: [7], 
[8], [9]. Looks like my implementation is the only one capable of 
storing access logs as well, e.g.:

{
     "_id" : ObjectId("4d98cc4f7abb95e59279e183"),
     "timeStamp" : ISODate("2011-04-03T19:36:47.339Z"),
     "server" : "localhost",
     "remote" : {
         "host" : "0:0:0:0:0:0:0:1",
         "user" : "tomcat",
         "addr" : "0:0:0:0:0:0:0:1"
     },
     "request" : {
         "uri" : "/manager/images/tomcat.gif",
         "protocol" : "HTTP/1.1",
         "method" : "GET",
         "sessionId" : "1C6357816D9EEFD31F6D9D154D87308A",
         "userAgent" : "Mozilla/5.0 (X11; U; Linux i686; pl-PL; 
rv:1.9.2.16) Gecko/20110323 Ubuntu/10.10 (maverick) Firefox/3.6.16",
         "referer" : "http://localhost:8080/manager/html"
     },
     "response" : {
         "contentLength" : NumberLong(1934),
         "statusCode" : 200
     }
}

We should now revise all available implementations and build final one 
based on best ideas from all of them. The only issue I see is 
integration testing: at least my tests require running MongoDB instance 
somewhere. This is a major drawback for both continuous integration of 
Lobgack extensions and for all developers, not necessarily interested in 
this particular extension.

Christian Trutz - thanks for creating the project structure.
