Utilities to sync Vim color scheme and iTerm profile

In Vim:

    :TerminalProfile [colorscheme] [light|dark]

will set the appropriate Vim color scheme, set the background, and then
use a little known terminal escape sequence hack to set the iTerm
profile using the `it2prof` shell script in `bin`.

If you want to sync the color scheme to the current iTerm profile, just
call `SetColorSchemeFromItermProfile()`, mapped to `<Leader>c`.
