[FIXED HUDSON-6966] Plugins with dependencies show wrong description on

installed plugins page.  DependencyClassLoader checks dependencies before
this plugin, so wrong index.jelly is found for plugins with dependencies.
Added implementation of findResources in DependencyClassLoader, and use
getResources to find the right index.jelly in PluginWrapper.getIndexPage().
