Add templates for test navigation commands
Kill reference to g:rails_modelines
Rename "path" to "path_additions"
Remove g:rails_mappings

Has anyone ever wanted to disable these wonderful, wonderful mappings?
I think not.
Remove obsolete modeline documentation
Localize dbext goofiness
Remove database config locking nonsense

This was added to allow for automatic creation of the database, a behavior
long since dropped.
Remove g:rails_syntax

Replace it with the undocumented g:rails_no_syntax.
Use g:rails_abbreviations to provide global abbreviations
Remove especially dumb/old abbreviations

I would like to prune this list much further.
