screen: Update for 256-color support

There's not a single box I log in to anymore on a regular basis that
doesn't have 256-color screen, so make that my default.  8 colors suck.

vim: Add bitbake support

Update my vimrc to treat bitbake recipes properly.  Add the bitbake syntax
project as a submodule.  Update the install script to do the right thing
with the new syntax files.
