Bump version to 1.154

This change bumps the MiniMaven and SciJava-common versions
*pre-emptively*, i.e. *just* before they are released. The reason is that
the new <dependencyManagement> section requires a new MiniMaven version
that can actually handle that, and the new MiniMaven version requires a
fix in SciJava-common's FileUtils to handle artifacts with classifiers
correctly.
