Changes to plugins_list, plugins_makefile and pw2wannier90.f90 to reflect the changes for the new release of Wannier90 (v3.0.0)
plugins_list and plugins_makefile are only updated with new links and correction of a typo. We have moved the flags that control the automatic generation of Wannier functions from Wannier90 to pw2wannier90. The new file reflects these changes.
