Bump version to 4.1.2-SNAPSHOT for development

Permission to use /openinv and /openender will grant online/offline access so that existing permissions configurations do not have to be redone. Users looking to implement the new permissions will need to deny them.

+## For Developers
+To compile, the relevant Craftbukkit/Spigot jars must be installed in your local repository using the install plugin.
+Ex: `mvn install:install-file -Dpackaging=jar -Dfile=spigot-1.8-R0.1-SNAPSHOT.jar -DgroupId=org.spigotmc -DartifactId=spigot -Dversion=1.8-R0.1-SNAPSHOT`
+
+To compile for a single version, specify the NMS revision you are targeting: `mvn -pl <NMS module> -am clean install`
+
+To compile for a set of versions, you'll need to use a profile. The only provided profile is `all`. Select a profile using the `-P` argument: `mvn clean package -am -P all`
+
+For more information, check out the [official Maven guide](http://maven.apache.org/guides/introduction/introduction-to-profiles.html).
+
+The final file is `target/OpenInv.jar`
