Include main.scss through the asset pipeline path resolver

[skateman]

When sprockets loads a file using the require directive, it usually goes through the config.assets.paths and searches for the given file. However, if you prepend the filename with a ./ as we did in f18e5d6 it will search only in the directory of the file with the directive.

This is all good until you don't want to override a file from a location with higher priority...

LGTM, merging when green :)

(Though .. if we ever add a npm package called main, this will break. (Until we can drop node_modules from asset_paths again.))

[skateman]

@himdel there's no such package in the NPM registry and let's hope it will not happen 😉

Creating one in a minute..

@himdel make sure it won't do anything useful, so we will never use it 😉
