fixing misc section, and file viewers. added misc_tag is_viewable() and MiscType.is_viewable() so not all misc objects get a View File button. Fixed wpstats to include wp_misc. other various enhancements to the wpviewer.js and viewer.views.py
Fixed wprefresh.py to accept 'skip' commands, also fixed wrun to handle scripts that need input (a dirty hack, but it works right now).
