Merge noserver into LaTeX-Box master
This is a big update!

This update brings two new options:
* g:LatexBox_latexmk_async (default: 0)
  If 1, use vimserver to allow asynchronuous compilation.
  The asynchronuous mode is not available on Windows.
  
  Note also that this changes the default behaviour of
  LaTeX-Box in that the async mode is not activated as
  default. The reason is to let portability be the priority.
  The default settings should work on all systems.
* g:LatexBox_latexmk_preview_continuously (default: 0)
  If 1, add '-pvc' flag to latexmk to let latexmk compile
  the document continuously whenever the document is
  updated (saved).
