Add Vim-Flavors.

I realized this morning that I can use Vundle and Vim-Flavors
simultaneously (duh).  Since Vim-Flavors is a superior packaging
system—in my option—I will gradually move over to it.  It also works
hand-in-hand with vim-vspec and testing plugins is a great idea.

I have an older branch where I attempted to move over wholesale to
Vim-Flavors but ran into plugins that did not support Vim-Flavors,
mostly due to versioning/tags.  I expect this attempt to be more
successful, which is why I'm doing this in my main branch.
Attempt to fix highlighting and CursorLine. Partial fix.
More repos moved from Vundle to Vim-Flavors.
