Stage 6 click-testing fixes and production setup

- file_attachment.rb: delete old upload directory before writing replacement
  files; fixes orphaned variants when filename or mime type changes
- assets/edit.html.erb: add file upload field and current file display;
  the form was previously empty and non-functional
- admin.css: fix button_to hover styling; buttons now show orange hover
  to signal interactivity
- test/controllers/users_controller_test.rb: assert input[type=submit]
  not anchor tag for destroy action (button_to change)
- test/test_helper.rb: add I18n.locale reset in setup block
- doc/rc.d_cccms: fix cccms_chdir, add start_precmd for log/pid dirs,
  PATH export for bash wrapper, user/pid/tcp_nopush unicorn fixes
- doc/INSTALL.md: new installation guide covering all non-obvious steps
- Remove parked search migration from doc/ (now in db/migrate/)
