about some problems compile failed and some hard code problems

1. JDK6 not support Integer.compile(int, int), so we use Integer.valueOf(int).compareTo(Integer.valueOf(int))

2. in com.kylinolap.job.hadoop.cube.NewBaseCuboidMapper, it imports org.eclipse.jdt.internal.core.Assert. but in pom.xml, org.eclipse.jdt dependency missed!

3. fix some hard code "/etc/kylin" in testcase CubeDevelopTestCase.

4. I update some dependency version...  oh!  It is not necessary, forget it !
