The javascript file name in app/views/pay/index.html.erb
'jquery.dataTables.js' is not consistent with the actual
JS file in /app/assets/javascripts 'jquery.dataTables.min.js'
This commit fixes by renaming the erring line in index.html.erb
no functional change here, but familiar Rails users will see view files in the
locations they expect. this also slightly simplifies controller code
there is one attendant change in the wiki at `rails_3/A1-SQL-Injection-Interpolation.md`
that I'm happy to make after the PR is merged.
