Added some aliases for Anchors.Clear*
Ensure ToString doesn't output IDs for classes of different types

While this breaks encapsulation, the IDs are by-object, so this can end
up reporting the same string for different objects if the types aren't
the same.
Split up Makefile dirs into separate variables
minor refactor
Use a non-newline print to ensure output is clean
Rename SetFilter from Filter
Called Require loading even if a module is loaded
Removed a bad variable
Actually invoke the filter when using LuaDependency
Added make targets for dot dependency graphs
