Wrong command was used to get the size of the image for E01 files. This
caused a shell error and a wrong default size returned. Fixed it.
Cleanup following the previous commit.
"Reports" tab was broken due to the addition of "be_feat_dir" parameter
to bc_get_reports() routine which is also called by all_reports tab. Added a
"None" parameter when called from "Reports" tab to fix it.
