Remove use of operator[] on a std::map, so no spurious elements get inserted. (fixes #464)

All uses of operator[] in guiConfigureWorld.cpp have been replaced
with .find() operations.

In some places, operator[] had been called with mod names of "Add-Ons"
or "N/A", which would insert a default-constructed ModSpec into the
list of add-on mods. In other places, the use of operator[] was safe
now, but it probably is safer for future changes to use .find()
everywhere.

Print missing mod dependencies on server start

i.e., not only the mod with missing dependencies, but also the missing
dependencies itself. (This already used to be the case before the mod
selection gui was added)

Also, mods with unsatisfied dependencies are no longer reported as
mods that could not be found.
