Custom layouts dir
[issue link]From this line https://github.com/nuxt/nuxt.js/blob/fbca3d7f78da1edb04bde21fddcc981f562f8fb4/lib/build.js#L148
It seems layouts can only be loaded from srcDir/layouts, is there any chance to add a layoutDir option in nuxt config? My use case is that I want to put all pages in srcDir but put layouts elsewhere.
