Fix coloring of shell/VimL/Python command substitutions

Browse Source 
Include the sh syntax for shell commands.
Make the matching on !v/!p work more accurately.
Highlight the !v/!p separately from the embedded Python/VimL.

AFAIK the only issue now is that "\`" escapes inside shell/VimL/Python
are not treated as bare "`" characters by the embedded syntax, but I
don't believe there's any way to fix that.
