Dependant ports editors/texworks and graphics/zathura are updated in
in D32265 and D32266, respectively. PORTREVISION of editors/gummi,
and net-mgmt/netmagis-www, and print/texlive-full are also incremented. For texlive-full,
texlive-full, though, I am not sure if I've done it correctly.
In the meanwhile, I didn't know what exactly to update since all ports called from theold patchfiles are deleted as I've brought configuration
flavour are excludingarguments into the main Makefile. This way, we can maintain the synctex engineport more
easily in future.
