This patch removes the remaining usages of M.on/M.off/M.emit
(functionality derived from moduleLoader.js in MobileFrontend) in
Minerva and continues the work of
Id990b0e1a53221d5c1cb3e3012aed0e27d801fc2 (patch for MobileFrontend).
This patch and the patch for MobileFrontend should be merged together as
they both depend on eachother.
