* src/main/java/com/tikal/jenkins/plugins/multijob/MultiJobBuilder.java: Fix MatrixBuild support for SubBuild

Build was used in multiple place instead of AbstractBuild which means it failed when the sub build was a MatrixBuild.
Symptom was that the MatrixBuild was started but never joined and did not showed up as active in the MultiJob page.

Fix access URL for sub job in MultiJobBuild view

When hudson is not at the top path of the webserver (ie htt://server/hudson/), the link to the sub job was broken.
Use ${rootURL} to fix this
