~/.vimrc: Put syntax, filetype and nocompatible on top.

Possibly among other things, this doesn't the reset the 'history'
setting to the default value (20) when setting 'nocompatible'.
And it's for the benefit of Mr. Kite or something.

.vimrc

" Have syntax highlighting and non-vi features
syntax on
filetype plugin indent on
set nocompatible
" Indent without helping me.
set autoindent
