More on l8 scripts (l8_lbw8, l8_lbw1)

Merging the two folders (scripts/l8_lbw8, scripts/l8_lbw1) for reasons described in commit cs150bf/vegas_devel@e45e595c32f2bc53498a03f427fb7943ddc512f0 
Updated scripts and notes. It might look like a big mess but most of the changes are actually just renaming files. Most of the changes that matter were made in *.py scripts.
