Adjust plugin code layout a lot

Including renaming big_file.vim and accompanying functions yet again, to
big_file_options.vim.

Trying to keep complex autocmd and mapping definitions on long lines
broken up semantically; definition and options on one line, patterns or
mapping key on the next, and the command to run on the last.

Also trying to make sure that <silent>, <buffer>, and <unique> are
applied in the correct places, and that all mapping commands are using
the :<C-U> idiom for the command prefix.
