Dynamic Search Path for ROOT Dictionary

Browse Source 
Added by default the dynamic search path '/usr/local/lib' to ROOT.
This is needed to find the necessary dictionaries for musrfit,
musrview, musrt0. Furthermore, added an option '--show-dynamic-path'
to these programs which allow the user to dump the currently used
dynamic search paths. This is potentially handy for diagnostics.
