Vim: Add custom command RunMake for smart Make

RunMake[!] will invoke either Make or Make! according to the
following criteria:

* If bang is given (i.e. RunMake!), run Make!
* For specified types such as latex or pandoc, run Make!
  (for disturbanceless background, by dispatch.vim)
* Otherwise, run Make (see output of cmake in the splitted pane)

This command is mapped to <F5> and <leader><F5>.
