Improved Formula Engine

* Does not try to forcefully cast column content to float
* Silences any errors during formula evaluation, you can look at
  `v:errmsg` to see if there was any error during the evaluation for
  debugging

 Markdown and ReST filetypes have automatically configured corners.
 
+> If you wish to override their configurations, it should be done in an after

+> In a `$VIM/after/ftplugin/markdown/custom.vim` you can add the following :

+> ```viml
+> let b:table_mode_corner='+'

    You can also define in a table header border how its content should be
    aligned, whether center, right or left by using a `:` character defined by
    `g:table_mode_align_char` option.
