wslua: fix errors in documentation, add notational conventions

Improve example with better formatting, clarification comments and more
common variable names.

Extend make-wsluarm.pl to support arguments containing underscores.
Fixes the description of dissect_tcp_pdus.

Change TvbRange.tvb(tvb) into tvbrange:tvb() and ByteArray.tvb(name)
into bytearray:tvb(name), these are really instance methods.
