window move, rotate, resize bindings

[josephholsten]

I'm just playing with what bindings feel most natural, but I'm wanting roughly:

" move cursor
map [w <C-W>h
map ]w <C-W>l
map [W <C-W>k
map ]W <C-W>j

" rotate 
map [<C-W> <C-W>R
map ]<C-W> <C-W>r

" resize
map [ow <C-W><
map ]ow <C-W>>
map [oW <C-W>-
map ]oW <C-W>+
map cow <C-W>=

obviously I need to implement repeat support
