LastFM "more" bug - Patch on github?

The site above indicates there is a patch that fixes the LastFM bug that opens a new window and doesn't let you get back to Music Cabinet main page. The changes in the .war file seem simple enough but this is a new area for me. I am running OSX 10.7.3 and it is my understanding that I should have everything I need to edit the .war and I guess recompile. Does one make the edits using Maven or something else? I have never used Maven, can anyone walk me through the process? Thanks in advance!

EDIT - I used Stuffit Expander to unpack the Subsonic.war file. I made the changes to the 2 files mentioned on the github link above using Text Editor. I typed the following into terminal - subsonic.warFolder wb$ mvn -P tomcat package

I got a missing POM error.
[ERROR] The goal you specified requires a project to execute but there is no POM in this directory (/Users/wb/Desktop/sample/subsonic.warFolder). Please verify you invoked Maven from the correct directory. -> [Help 1]

I found a POM.xml file on the github site here -
https://github.com/hakko/musiccabinet/b ... er/pom.xml

Do I copy this POM.xml to text editor, save and drop into the WAR folder before running mvn command? Admittedly I really don't know what I am doing here but it looks pretty straight forward. Any suggestions on how to complete this?

I have been using Music Cabinet for a few days now and this Mod is awesome!
