set include, includeexpr and path

This enables:

• gf normal command over module name in the import section
• ]i, ]I normal commands
• :find command to navigate through all the source files

I'm currently not actively working on this so maybe @Arthur-Xavier can also have a look.

These are some nice improvements there! Thanks a lot! ]i and ]I are fantastic!

Tested it all and everything works fine as of vim-8.0.525 and nvim-0.2.1-359. It's a shame, however, that imports under bower_components could only be located with gf after I removed bower_components from my wildignore list.

Do you know perhaps any solution for that?

vim normal mode commands are are linked to command, I think that gf is sharing code with find. But I couldn't reproduce your issue even with se wig+=*.purs neither with se wig=bower_components/** (and set acd=0).

What you could do is to map gf to a function which temporarily changes wildignore:

fun! Gf()
  let wig = &wig
  set wig -= bower_components
  normal "gf"
  let &wig = wig
endfun

That's a witty trick. Works great! Unfortunately I had to use it as <leader>gf. Otherwise it would infinitely recurse.
