bugs in vim scripting highlighting

[Mikolaj Machowski]

Hello,

Noticed two bugs in vim script highlighting:

1. xnoremap and snoremap are not fully recognized. Compare highlighting
   of those three lines:

      inoremap <buffer> <silent> <expr> <C-C> <SID>CtrlC()
      xnoremap <buffer> <silent> <expr> <C-C> <SID>CtrlC()
      snoremap <buffer> <silent> <expr> <C-C> <SID>CtrlC()

   Arguments of xnoremap and snoremap aren't highlighted

2. Function element addButton is highlighted as error:

    function! forms#form.addButton(fname, flabel, fvalue, hotkey, listener)

   But it works (as in forms.vim). the same apply to call call.
