Allow Vim mouse to work when within tmux/screen

Vim does not set t_RV correctly for TERM of screen-256color, so set it
explicitly which will allow it to correctly detect the value of ttymouse
(and hopefully set it to xterm2 based on the value of v:termresponse).
Move off vim-rails fork now that pull request is merged
Remove excessive comments
Use sqlanywhere syntax instead of sqloracle

Since we use Postgres this syntax is more representative of what we
expect.
Include vim-cdo as a submodule and update version
Map <leader>i to insert story ID into git commit msg
Don't store options in Vim sessions

Add vim-rake so :A (among other things) works in non-Rails Ruby projects
ackrc doesn't belong here
Add <leader>cp to copy just file path (w/o line number)
Remove shortcuts for typing model names

Else it's nearly impossibly to type "E.".
