The idea is to use a Layered Asset File-system (modules/assetfs/layered.go) For example: when there are 2 layers: "custom", "builtin", when access to asset "my/page.tmpl", the Layered Asset File-system will first try to use "custom" assets, if not found, then use "builtin" assets. This approach will hugely simplify a lot of code, make them testable. Other changes: * Simplify the AssetsHandlerFunc code * Simplify the `gitea embedded` sub-command code --------- Co-authored-by: Jason Song <i@wolfogre.com> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
