Remove unneeded @Override annotations
Now works with Tomcat Valves to send access logs

Initial work on Tomcat AccessLog Valve

Put jar-with-dependancies into $CATALINA_HOME/lib/

Add a new Valve into your $CATALINA_BASE/conf/server.xml
``` xml
...
<Valve className="com.stuartwarren.logit.tomcatvalve.ZmqAppender"
               layout="com.stuartwarren.logit.tomcatvalve.Layout"
               socketType="PUSHPULL"
               endpoints="tcp://localhost:2120"
               bindConnect="CONNECT"
               linger="1000"
               sendHWM="1000"
               layoutType="logstashv1"
               iHeaders="Referer,User-Agent"
               oHeaders=""
               cookies=""
               tags="tag1,tag2,tag3"
               fields="field1:value1,field2:value2,field3:value3" />
...
```

Produces logs like:
```
{"message":"GET /?testthing=oeuai HTTP/1.1 304","tags":["tag1","tag2","tag3","valve"],"@timestamp":"2013-10-19T15:47:20.210Z","field3":"value3","field2":"value2","level":"INFO","http":{"request_protocol":"HTTP/1.1","response_headers":{},"request_querystring":"testthing=oeuai","remote_user":null,"request_headers":{"Referer":null,"User-Agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36"},"response_size":0,"response_status":304,"request_parameters":{"testthing":["oeuai"]},"request_uri":"/","remote_host":"192.168.1.208","request_method":"GET","response_duration":28,"cookies":{}},"hostname":"precise64","field1":"value1","@version":"1","user":"tomcat7"}
```
Fixed up project to work with tomcat better

Set up pom to generate 2 jars
- logit
- logit-tomcatvalve

Provided better Vagrant file to demo logit with tomcat
Vagrant now uses config in test/resources
Can handle tomcat jul logging and accesslog valve at the same time now
Update README and pom

travis didn't deploy all the expected artifacts
test another change to pom
Merge pull request #34 from stuart-warren/next

Next - Add Tomcat Valve logging feature
